+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+A collection of 3D printing utilities for generating personalized STL files using **Python + OpenSCAD**. The repository contains two main subprojects:
+
+1. **Nameplates** - Batch nameplate and zipper pull generator
+2. **Key caps** - Mechanical keyboard keycap scaling utilities
+
+All projects use OpenSCAD as the 3D modeling engine, invoked via Python scripts or standalone SCAD files.
+

+
+## Critical Dependencies
+
+### OpenSCAD Installation
+- **Path**: `C:\Program Files\OpenSCAD\openscad.exe` (hardcoded in Python scripts)
+- **Download**: https://openscad.org/downloads.html
+- **Update path** in scripts if installed elsewhere (see `generate_nameplates.py:36`, `generate_zipper_pulls.py:36`)
+
+### Font Requirements (Nameplates/Zipper Pulls Only)
+- **Font**: Fordscript cursive font (`Nameplates/Fordscript.ttf`)
+- **Installation**: Must be installed in Windows (right-click → Install for all users)
+- **Critical**: OpenSCAD references fonts by system name, not file path
+- **Verification**: After install, restart OpenSCAD before generating files
+
+## Key Commands
+
+### Nameplates
+```bash
+# Generate all nameplates (38mm height, no hole)
+cd Nameplates
+python generate_nameplates.py
+
+# Output: output_stl/*.stl
+```
+
+### Zipper Pulls
+```bash
+# Generate all zipper pulls (100mm × 34mm total, 4mm hole with 1mm clearance)
+cd Nameplates
+python generate_zipper_pulls.py
+
+# Output: zipper-pulls/*.stl
+```
+
+### Key Caps
+```powershell
+# Render scaled keycap (command line)
+& "C:\Program Files\OpenSCAD\openscad.exe" -o "output.stl" "Body5_scaled_FIXED.scad"
+
+# Or: Open in OpenSCAD GUI, adjust parameters, press F6 to render, export STL
+& "C:\Program Files\OpenSCAD\openscad.exe" "Body5_scaled_FIXED.scad"
+```
+
+### Manual OpenSCAD Testing
+```powershell
+# Test single nameplate
+& "C:\Program Files\OpenSCAD\openscad.exe" -D 'name="TestName"' -o test_output.stl nameplate_template.scad
+
+# Test single zipper pull
+& "C:\Program Files\OpenSCAD\openscad.exe" -D 'name="TestName"' -o test_output.stl zipper_pull_template.scad
+
+# Preview in GUI (edit parameters at top of file)
+& "C:\Program Files\OpenSCAD\openscad.exe" nameplate_template.scad
+```
+
+## Architecture Overview
+
+### Nameplates vs Zipper Pulls
+
+Both use the same two-layer oval design (white base + blue top with engraved text) but differ in dimensions and features:
+
+| Feature | Nameplates | Zipper Pulls |
+|---------|-----------|-------------|
+| Template | `nameplate_template.scad` | `zipper_pull_template.scad` |
+| Generator | `generate_nameplates.py` | `generate_zipper_pulls.py` |
+| Total Size (W×H) | 100mm × 38mm | 100mm × 34mm |
+| Blue Layer Size | 96mm × 34mm | 96mm × 30mm |
+| White Base Offset | 2mm all sides | 2mm all sides |
+| Font Size | 30mm | 13mm |
+| Hole | None | 4mm diameter, left side |
+| Hole Clearance | N/A | 1mm from white base edge |
+| Output Directory | `output_stl/` | `zipper-pulls/` |
+| Use Case | Display nameplates | Zipper/bag attachments |
+
+**Important**: These are separate templates and scripts. Modifying one does not affect the other.
+
+### Pipeline Architecture
+
+```
+names.txt
+    ↓
+Python Generator Script (reads names, iterates)
+    ↓
+OpenSCAD CLI (renders each name via template)
+    ↓
+STL Files (output to respective directories)
+```
+
+**Key Pattern**: Python script calls OpenSCAD subprocess for each name:
+```python
+cmd = [
+    r'C:\Program Files\OpenSCAD\openscad.exe',
+    '-D', f'name="{escaped_name}"',  # Override parameter
+    '-o', output_file,                # Output STL path
+    template_file                     # SCAD template
+]
+subprocess.run(cmd, capture_output=True, text=True, check=True)
+```
+
+### OpenSCAD Template Pattern
+
+All SCAD templates follow this structure:
+```scad
+// 1. Parameters (overridable via -D flag)
+name = "NAME";
+oval_width = 100;
+// ... more parameters
+
+// 2. Modules (reusable geometry functions)
+module oval(width, height, depth) { ... }
+module base_layer() { ... }
+module top_layer() { ... }
+
+// 3. Assembly module
+module nameplate() {
+    base_layer();
+    top_layer();
+}
+
+// 4. Execution (builds the model)
+nameplate();
+```
+
+## Project-Specific Conventions
+
+### Name Sanitization
+Python scripts convert names to safe filenames:
+- Removes special characters (keeps alphanumeric, spaces, hyphens, underscores)
+- Replaces spaces with underscores
+- Escapes quotes for shell: `name.replace('"', '\\"')`
+- Example: `"John Doe"` → `John_Doe.stl`
+
+### Two-Layer Design Philosophy
+- **White base layer**: Structural foundation, extends beyond blue layer by `base_offset` (2mm)
+- **Blue top layer**: Visual layer with engraved text
+- **Text engraving**: Cuts completely through blue layer (`text_depth = top_thickness = 1mm`) to expose white base underneath
+- **Result**: White text on blue background
+
+### Hole Positioning (Zipper Pulls)
+Hole is positioned on left side with clearance from white base edge:
+```scad
+white_width = oval_width + base_offset*2;
+hole_x = -(white_width/2) + (hole_diameter/2) + hole_clearance;
+// For 96mm blue + 2mm offset = 100mm white, 4mm hole, 1mm clearance:
+// hole_x = -50 + 2 + 1 = -47mm from center
+```
+
+**Critical**:
+- `hole_clearance` must be sufficient to prevent hole from breaking through oval edge. Current value (1mm) tested and verified.
+- Hole is positioned relative to **white base width**, not blue layer width, to ensure it stays within the white outline.
+
+## Common Workflows
+
+### Add New Names to Both Systems
+1. Edit `Nameplates/names.txt`, add name on new line
+2. Run both generators:
+   ```bash
+   cd Nameplates
+   python generate_nameplates.py     # Creates nameplate
+   python generate_zipper_pulls.py   # Creates zipper pull
+   ```
+3. Find STLs in `output_stl/` and `zipper-pulls/` respectively
+
+### Adjust Zipper Pull Hole Clearance
+If hole is too close to edge or breaking through:
+1. Edit `zipper_pull_template.scad`, line 17:
+   ```scad
+   hole_clearance = 1; // Increase this value
+   ```
+2. Regenerate all zipper pulls:
+   ```bash
+   python generate_zipper_pulls.py
+   ```
+
+**Note**: Hole clearance is measured from the **white base edge**, not the blue layer edge.
+
+### Create Custom Dimension Variant
+To create a new variant (e.g., smaller nameplates):
+1. Copy existing template: `nameplate_template.scad` → `nameplate_small_template.scad`
+2. Modify dimensions at top of new file
+3. Copy generator script: `generate_nameplates.py` → `generate_nameplates_small.py`
+4. Update generator to use new template and output directory:
+   ```python
+   template_file = "nameplate_small_template.scad"
+   output_dir = "output_stl_small"
+   ```
+
+### Scale Keycaps for Different Tolerances
+1. Open `Key caps/Body5_scaled_FIXED.scad` in OpenSCAD GUI
+2. Adjust `body_scale_xy` parameter at top (default: 0.98 = 98%)
+   - Too tight: decrease to 0.97 (3% reduction)
+   - Too loose: increase to 0.99 (1% reduction)
+3. Press `F5` for preview, `F6` for full render
+4. Export via `File > Export > Export as STL`
+5. Test print and iterate
+
+See `Key caps/README_scaling.md` for detailed keycap scaling workflow.
+
+## Troubleshooting
+
+### Font Not Found (Nameplates/Zipper Pulls)
+**Symptom**: Text is missing or uses default font in generated STLs.
+
+**Fix**:
+1. Install `Fordscript.ttf`: Right-click → "Install for all users"
+2. Restart OpenSCAD if running
+3. Test with manual command:
+   ```powershell
+   & "C:\Program Files\OpenSCAD\openscad.exe" -D 'name="Test"' -o test.stl nameplate_template.scad
+   ```
+4. Open `test.stl` in slicer and verify text appears
+
+### OpenSCAD Path Not Found
+**Symptom**: `FileNotFoundError: OpenSCAD not found`
+
+**Fix**: Update hardcoded path in generator scripts:
+```python
+# In generate_nameplates.py and generate_zipper_pulls.py, line 36:
+cmd = [
+    r'C:\Program Files\OpenSCAD\openscad.exe',  # ← Update this path
+    # ...
+]
+```
+
+### Zipper Pull Hole Breaking Through Edge
+**Symptom**: Hole intersects with oval edge, causing weak point or break.
+
+**Fix**: Increase `hole_clearance` in `zipper_pull_template.scad`:
+```scad
+hole_clearance = 1.5; // Increase from 1mm to 1.5mm
+```
+Then regenerate all zipper pulls.
+
+**Note**: Ensure hole clearance is measured from the white base edge (100mm total width), not the blue layer edge (96mm).
+
+### Keycap Stem Scaled Incorrectly
+**Symptom**: Cherry MX stem doesn't fit switch after scaling.
+
+**Cause**: Using wrong SCAD file (non-FIXED version requires manual stem positioning).
+
+**Fix**: Always use `Body5_scaled_FIXED.scad` which uses centered import approach. The stem preservation region is automatically centered at origin.
+
+## Advanced Customization
+
+### Add Custom Parameter to Templates
+To add a new parameter (e.g., border thickness):
+
+1. Add parameter to template:
+   ```scad
+   border_thickness = 0.5; // New parameter
+   ```
+
+2. Use in geometry:
+   ```scad
+   module base_layer() {
+       difference() {
+           oval(oval_width, oval_height, base_thickness);
+           // Cut border groove
+           translate([0, 0, base_thickness - border_thickness])
+               oval(oval_width - 4, oval_height - 4, border_thickness + 0.1);
+       }
+   }
+   ```
+
+3. Pass from Python script (optional):
+   ```python
+   cmd = [
+       r'C:\Program Files\OpenSCAD\openscad.exe',
+       '-D', f'name="{escaped_name}"',
+       '-D', f'border_thickness={thickness}',  # Override parameter
+       '-o', output_file,
+       template_file
+   ]
+   ```
+
+### Batch Generate Multiple Sizes
+Modify generator script to loop over multiple configurations:
+
+```python
+configs = [
+    {"template": "nameplate_template.scad", "width": 100, "height": 38},
+    {"template": "nameplate_template.scad", "width": 80, "height": 30},
+    {"template": "nameplate_template.scad", "width": 60, "height": 23},
+]
+
+for name in names:
+    for config in configs:
+        output_file = f"{config['width']}x{config['height']}_{safe_name}.stl"
+        cmd = [
+            r'C:\Program Files\OpenSCAD\openscad.exe',
+            '-D', f'name="{escaped_name}"',
+            '-D', f'oval_width={config["width"]}',
+            '-D', f'oval_height={config["height"]}',
+            '-o', output_file,
+            config["template"]
+        ]
+        subprocess.run(cmd, ...)
+```
+
+## Development Reference
+
+### OpenSCAD Command Line Flags
+```powershell
+# Override parameter
+-D 'name="value"'
+
+# Output file
+-o output.stl
+
+# Check syntax (no output)
+--check
+
+# Verbose output
+--verbose
+
+# Clear cache (useful when changing imports)
+--clear-cache
+
+# Version info
+--version
+```
+
+### Python Subprocess Pattern
+All generators use the same pattern:
+```python
+result = subprocess.run(
+    cmd,
+    capture_output=True,  # Capture stdout/stderr
+    text=True,            # Return strings, not bytes
+    check=True            # Raise CalledProcessError on non-zero exit
+)
+```
+
+Error handling:
+```python
+try:
+    subprocess.run(cmd, capture_output=True, text=True, check=True)
+except subprocess.CalledProcessError as e:
+    print(f"Error: {e.stderr}")
+except FileNotFoundError:
+    print("OpenSCAD not found. Install from https://openscad.org")
+```
+
+## File Organization Guidelines
+
+### When to Create New Template vs Modify Existing
+
+**Create New Template** if:
+- Fundamentally different design (e.g., adding holes, changing shape)
+- Different use case (nameplates vs zipper pulls)
+- Need to maintain both versions simultaneously
+
+**Modify Existing Template** if:
+- Adjusting dimensions only
+- Tweaking existing features
+- Single-use or temporary change
+
+### Output Directory Naming
+- Use descriptive names: `output_stl/`, `zipper-pulls/`
+- Keep separate output directories for different variants
+- Never mix different variants in the same directory (prevents confusion)
+
+### Generator Script Naming
+- Match template name: `generate_nameplates.py` uses `nameplate_template.scad`
+- Be explicit: `generate_zipper_pulls.py` not `generate_zippers.py`
+- One template per generator for clarity
+
+## 3D Printing Notes
+
+### Recommended Slicer Settings
+- **Material**: Two colors (white + blue PLA recommended)
+- **Layer Height**: 0.1-0.2mm for clean text details
+- **Infill**: 20-30% (thin parts don't need much)
+- **Supports**: Not needed (flat design, print as modeled)
+- **Orientation**: Print flat on bed
+- **Bed Adhesion**: Brim or raft recommended for thin parts
+- **First Layer**: Critical for thin 1.5mm base - ensure good adhesion
+
+### Multi-Color Printing
+Two approaches:
+1. **Filament swap**: Print white base, pause, swap to blue, continue
+2. **Two prints**: Print white base separately, print blue top, glue together
+
+**Important**: Text must be fully engraved through blue layer to show white underneath.
+
+#### M600 Filament Change Height
+When using M600 command for automatic filament change in slicer:
+- **Base layer thickness**: 1.5mm
+- **Actual M600 height**: 1.5mm + one layer height
+- **Reason**: M600 triggers BEFORE the specified layer is printed. If set to exactly 1.5mm, the slicer will print one solid white layer at 1.5mm, then trigger M600, then start the blue outline and text.
+- **Example**: With 0.2mm layer height, set M600 at 1.7mm (1.5 + 0.2) to ensure filament change happens at the correct layer.
+- **Verification**: After slicing, verify that the layer immediately after M600 begins the blue top layer, not another white layer.
+
+## Project-Specific Quirks
+
+### Why Two Separate Templates for Nameplates/Zipper Pulls?
+- Different dimensions (38mm vs 34mm height)
+- Zipper pulls need hole, nameplates don't
+- Maintains backward compatibility with existing nameplate output
+- Allows independent evolution of each variant
+
+### Why Hardcoded OpenSCAD Path?
+- Windows standard installation location is consistent
+- Avoids PATH environment complexity
+- Easy to update in one place per script
+- Future: Consider environment variable or config file
+
+### Why Manual Font Installation?
+- OpenSCAD uses system font registry, not file paths
+- Ensures consistent font rendering across machines
+- Font must be available to OpenSCAD process
+- No programmatic workaround exists
+
+### Keycap Stem Preservation Algorithm
+- Circular region around stem preserved at 100% scale
+- Rest of keycap scaled down for better fit
+- Cherry MX stem is exactly 4mm × 4mm by spec (must not scale)
+- Circular preservation accommodates off-brand switch tolerances
+- See `Key caps/CLAUDE.md` for detailed algorithm explanation

+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is an OpenSCAD project for scaling 3D-printed mechanical keyboard keycaps while preserving the Cherry MX stem dimensions. The project contains scripts to reduce keycap body dimensions for better socket fit while maintaining the exact 4mm × 4mm stem cross dimensions required for Cherry MX switches.
+
+## Key Commands
+
+### Rendering STL Files
+
+On Windows, OpenSCAD is typically installed at `C:\Program Files\OpenSCAD\openscad.exe`. Use Git Bash path format:
+
+```bash
+# Render a SCAD file to STL
+"/c/Program Files/OpenSCAD/openscad.exe" -o "output.stl" "input.scad"
+
+# Clear cache and render (recommended when changing imports)
+"/c/Program Files/OpenSCAD/openscad.exe" --clear-cache -o "output.stl" "input.scad"
+```
+
+### Verify OpenSCAD Installation
+
+```bash
+# Check if OpenSCAD is installed
+if exist "C:\Program Files\OpenSCAD\openscad.exe" echo Found at C:\Program Files\OpenSCAD\openscad.exe
+```
+
+## Project Architecture
+
+### Main Scripts
+
+- **`Body5_scaled_FIXED.scad`**: The primary working script that uses a centered-import approach. This is the recommended version for scaling keycaps.
+- **`Body5_scaled.scad`**: Earlier version that manually positions the stem preservation cylinder using explicit X/Y coordinates.
+- **`Body5_test_circle.scad`**: Test script with exaggerated parameters (larger cylinder) to verify the circular stem preservation is working.
+- **`test_cylinder.scad`**: Simple cylinder rendering test for OpenSCAD verification.
+
+### STL Files
+
+- **`Body5.stl`**: The original keycap model that gets imported and processed by the SCAD scripts.
+- **`Body2.stl`**: Alternative keycap model.
+- **Generated STL files**: Output from rendering the SCAD scripts (e.g., `Body5_scaled_98percent.stl`).
+
+### Scaling Algorithm
+
+The scripts use a two-part union approach:
+
+1. **Scaled Body with Cutout**: The entire keycap is scaled down by `body_scale_xy`, then a cylinder is subtracted where the stem should be
+2. **Unscaled Stem Region**: A cylinder intersection preserves the original stem region at 100% scale
+3. **Union**: Both parts are merged, creating a keycap with scaled body but original stem dimensions
+
+The `_FIXED` version centers the model at the origin before operations, making cylinder placement simpler. The non-FIXED version requires manual positioning of the preservation cylinder using `stem_x` and `stem_y` coordinates.
+
+### Critical Parameters
+
+- **`body_scale_xy`**: X/Y scaling factor (typically 0.97-0.99 for 1-3% reduction)
+- **`body_scale_z`**: Z scaling factor (keep at 1.00 to maintain keycap height)
+- **`stem_diameter`**: Diameter of circular preservation region (default: 5.5mm)
+- **`stem_height`**: Height of stem region (default: 8.0mm)
+- **`$fn`**: OpenSCAD circle resolution (64-128, higher = smoother but slower)
+
+### Centering Approach (FIXED version)
+
+The `centered_import()` module translates the imported STL by `[-209, -223.5, -4.9]` to center it at the origin. These values were determined by analyzing the original STL's bounding box. This allows stem operations to use simple `cylinder()` calls at the origin rather than calculating offsets.
+
+## Development Workflow
+
+1. Modify SCAD script parameters (typically just `body_scale_xy`)
+2. Render to STL using OpenSCAD command line or GUI (F5 preview, F6 full render in GUI)
+3. Import STL into slicer and print test keycap
+4. Measure fit and iterate on scaling factor
+5. Typical iteration: start at 0.98, adjust by 0.01 increments based on fit testing
+
+## Important Notes
+
+- The Cherry MX stem cross is exactly 4mm × 4mm by specification and must not be scaled
+- The circular preservation region accommodates off-brand switches that may have slightly different tolerances
+- All SCAD scripts expect `Body5.stl` (or specified STL file) to be in the same directory
+- Rendering is computationally intensive due to importing the STL twice (once for scaling, once for stem preservation)

+# Keycap Scaling Guide
+
+## Quick Start
+
+1. **Open the script**: Open `Body5_scaled.scad` in OpenSCAD
+2. **Adjust scaling**: Edit the `body_scale_xy` parameter at the top (default: 0.98 = 98%)
+3. **Preview**: Press `F5` to see a quick preview
+4. **Render**: Press `F6` to fully render (required before export)
+5. **Export**: Go to `File > Export > Export as STL`
+6. **Test print**: Print and check the fit
+7. **Iterate**: Adjust the scale parameter and repeat if needed
+
+## Key Parameters
+
+### `body_scale_xy`
+- **Default**: `0.98` (98% of original size)
+- **Purpose**: Scales the X and Y dimensions of the keycap body
+- **Recommendations**:
+  - Start with `0.98` for a 2% reduction
+  - If too tight: try `0.97` (3% reduction)
+  - If too loose: try `0.99` (1% reduction)
+  - Fine-tune: use `0.975`, `0.985`, etc.
+
+### `body_scale_z`
+- **Default**: `1.00` (no scaling)
+- **Purpose**: Scales the Z (height) dimension
+- **Recommendation**: Keep at `1.00` to maintain keycap height
+
+### Stem Parameters (Advanced)
+Only adjust these if the stem preservation isn't working correctly:
+
+- `stem_diameter`: Diameter of the circular preservation region (default: 5.5mm)
+- `stem_height`: Height of the stem (default: 4.0mm)
+- `stem_z_position`: Vertical position offset (default: -2.0mm)
+- `$fn`: Circle smoothness (default: 64, range: 32-128)
+
+## How It Works
+
+The script uses a two-part approach:
+
+1. **Scaled Body**: The entire keycap is scaled down by your chosen percentage, BUT a circular region around the stem is cut out
+2. **Original Stem**: The circular stem region is preserved at 100% scale (keeping the 4mm × 4mm Cherry MX cross dimensions)
+3. **Combined**: Both parts are merged together
+
+This ensures:
+- ✅ The outer keycap body fits better in sockets (scaled down)
+- ✅ The Cherry MX stem remains exactly 4mm × 4mm (unscaled)
+- ✅ The circular region around the stem is preserved (for off-brand switches)
+- ✅ The stem stays centered and properly positioned
+
+## Workflow for Iterative Testing
+
+1. Export STL with `body_scale_xy = 0.98`
+2. Slice and print the keycap
+3. Test fit on your keyboard
+4. **If too tight**: Decrease scale (try 0.97)
+5. **If too loose**: Increase scale (try 0.99)
+6. **If just right**: You're done!
+
+## Troubleshooting
+
+### The stem looks wrong or is scaled
+- The circular stem region might not be positioned correctly
+- Measure your stem in the original STL
+- Adjust `stem_z_position`, `stem_diameter`, or `stem_height`
+- If the circle is too jagged, increase `$fn` to 128
+
+### The keycap won't render
+- Make sure `Body5.stl` is in the same folder as the `.scad` file
+- Check for errors in the OpenSCAD console (bottom of window)
+
+### Rendering is slow
+- This is normal! The script imports the STL twice
+- `F5` preview is fast but lower quality
+- `F6` render is slow but required for STL export
+- Consider reducing the preview quality in OpenSCAD preferences
+
+### The seam between body and stem is visible
+- This is usually not noticeable in the printed part
+- If needed, increase `stem_diameter` by 0.5mm increments (try 6.0mm or 6.5mm)
+
+## File Structure
+
+```
+Key caps/
+├── Body5.stl              # Original keycap STL
+├── Body5_scaled.scad      # OpenSCAD scaling script
+└── README_scaling.md      # This guide
+```
+
+## Export Settings
+
+When exporting STL from OpenSCAD:
+- File format: STL (binary is smaller, ASCII is more compatible)
+- Units: millimeters (mm)
+
+## Next Steps
+
+After exporting your scaled STL:
+1. Import into your slicer (Cura, PrusaSlicer, etc.)
+2. Use typical keycap print settings:
+   - Layer height: 0.1-0.2mm
+   - Infill: 15-20%
+   - Supports: Probably not needed for most keycaps
+3. Print and test!
+
+---
+
+**Note**: The Cherry MX stem dimensions (4mm × 4mm) are standardized. The script is designed to preserve these exactly, so you should only need to adjust the `body_scale_xy` parameter for tolerance testing.

+# AI Coding Instructions for Nameplates Generator
+
+## Project Overview
+
+A batch 3D nameplate generator using **Python + OpenSCAD**. Reads names from text file, generates parametric two-layer oval nameplates with engraved text, outputs STL files for 3D printing.
+
+**Design**: White base (1.5mm) + blue top layer (1mm) with text engraved through blue layer to expose white underneath.
+
+## Critical Dependencies
+
+### OpenSCAD Installation
+- **Path**: `C:\Program Files\OpenSCAD\openscad.exe` (hardcoded in line 36 of `generate_nameplates.py`)
+- Download: https://openscad.org/downloads.html
+- **Must update path** if installed elsewhere
+
+### Font Requirements (CRITICAL)
+- **Font**: Fordscript cursive font (`Fordscript.ttf` in project root)
+- **Installation**: Must be installed in Windows (right-click → Install for all users)
+- **Why**: OpenSCAD references fonts by name, not file path
+- **Reference in SCAD**: `font="Fordscript"` (line 44 of `nameplate_template.scad`)
+- **Path hardcoded**: `font_file = "C:/Users/Fred/claude/Fordscript.ttf"` in SCAD (line 10) - informational only, not used by OpenSCAD
+
+## Architecture & Data Flow
+
+```
+names.txt → generate_nameplates.py → OpenSCAD CLI → output_stl/*.stl
+                                       ↑
+                                nameplate_template.scad
+```
+
+### Pipeline
+1. **Input**: `names.txt` (one name per line, UTF-8 encoded)
+2. **Processing**: Python script iterates, calling OpenSCAD for each name
+3. **OpenSCAD**: Renders 3D model from parametric template
+4. **Output**: Individual STL files in `output_stl/` directory
+
+### Key Files
+- `generate_nameplates.py` - Batch processor, subprocess orchestration
+- `nameplate_template.scad` - Parametric OpenSCAD template
+- `names.txt` - Input data (plain text, one name per line)
+- `output_stl/` - Generated STL files (created automatically)
+- `Fordscript.ttf` - Custom font (must be installed)
+
+## Critical Developer Workflows
+
+### Generate All Nameplates
+```bash
+python generate_nameplates.py
+```
+
+### Test Single Nameplate (Manual)
+```powershell
+# PowerShell syntax
+& "C:\Program Files\OpenSCAD\openscad.exe" -D 'name="TestName"' -o test_output.stl nameplate_template.scad
+
+# Or from CMD
+"C:\Program Files\OpenSCAD\openscad.exe" -D "name=\"TestName\"" -o test_output.stl nameplate_template.scad
+```
+
+### Preview in OpenSCAD GUI
+```powershell
+# Open template in GUI for visual editing
+& "C:\Program Files\OpenSCAD\openscad.exe" nameplate_template.scad
+```
+
+Then manually edit `name` parameter at top of file to preview different text.
+
+### Validate Font Installation
+```powershell
+# Check if font is installed
+Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts" | Select-String "Fordscript"
+
+# Or check fonts directory
+ls $env:WINDIR\Fonts\Fordscript*
+```
+
+## Project-Specific Conventions
+
+### Name Sanitization
+Python script converts names to safe filenames:
+- Removes special characters (keeps alphanumeric, spaces, hyphens, underscores)
+- Replaces spaces with underscores
+- Example: `"John Doe"` → `John_Doe.stl`
+
+### OpenSCAD Command Pattern
+```python
+cmd = [
+    r'C:\Program Files\OpenSCAD\openscad.exe',
+    '-D', f'name="{escaped_name}"',  # Set variable
+    '-o', output_file,                # Output file
+    template_file                     # Input SCAD file
+]
+```
+
+**Key flags**:
+- `-D name="value"` - Override parameter in SCAD file
+- `-o file.stl` - Output file path
+- No flag for input file (positional argument)
+
+### SCAD Template Structure
+```scad
+// Parameters (overridable via -D flag)
+name = "NAME";
+oval_width = 100;
+oval_height = 38;
+// ... more parameters
+
+// Modules (functions)
+module oval(width, height, depth) { ... }
+module base_layer() { ... }
+module top_layer() { ... }
+module nameplate() { ... }
+
+// Execution (builds the model)
+nameplate();
+```
+
+## Common Pitfalls
+
+### Font Not Found Error
+**Symptom**: OpenSCAD renders but text is missing or uses default font.
+
+**Causes**:
+1. Font not installed in Windows (right-click TTF → Install)
+2. Font name mismatch (must be exactly "Fordscript" in SCAD)
+3. OpenSCAD needs restart after font installation
+
+**Fix**: Install font, restart OpenSCAD, verify with manual test.
+
+### Special Characters in Names
+**Symptom**: Subprocess error or malformed STL.
+
+**Cause**: Shell escaping issues with quotes, backslashes, etc.
+
+**Current handling**: `escaped_name = name.replace('"', '\\"')` (line 33)
+
+**Extension**: Add more sanitization if needed:
+```python
+# Escape more shell-sensitive characters
+escaped_name = name.replace('"', '\\"').replace('\\', '\\\\')
+```
+
+### OpenSCAD Path Issues
+**Symptom**: `FileNotFoundError: OpenSCAD not found`.
+
+**Fix**: Update hardcoded path in `generate_nameplates.py:36`:
+```python
+cmd = [
+    r'C:\Program Files\OpenSCAD\openscad.exe',  # ← Update this
+    # ...
+]
+```
+
+**Better approach**: Use environment variable or config file:
+```python
+OPENSCAD_PATH = os.getenv('OPENSCAD_PATH', r'C:\Program Files\OpenSCAD\openscad.exe')
+```
+
+## Modifying Dimensions
+
+All dimensions in `nameplate_template.scad` (lines 6-12):
+
+| Parameter | Current Value | Purpose |
+|-----------|---------------|---------|
+| `oval_width` | 100mm | Overall width |
+| `oval_height` | 38mm | Overall height (proportional) |
+| `base_thickness` | 1.5mm | White layer thickness |
+| `top_thickness` | 1mm | Blue layer thickness |
+| `base_offset` | 2mm | White extension beyond blue |
+| `text_size` | 15mm | Font size |
+| `text_depth` | 1mm | Engraving depth (full blue layer) |
+
+### Maintaining Proportions
+Height typically 38% of width for aesthetic oval shape:
+```scad
+oval_height = oval_width * 0.38;
+```
+
+### Text Depth Critical
+`text_depth` must equal `top_thickness` to engrave through entire blue layer:
+```scad
+text_depth = 1; // Must match top_thickness for full engraving
+```
+
+If `text_depth < top_thickness`, text won't reach white base. If `text_depth > top_thickness`, text cuts into white base (undesirable).
+
+## Extending the Template
+
+### Add New Shape Option
+```scad
+// Add rectangle module
+module rectangle(width, height, depth) {
+    cube([width, height, depth], center=true);
+}
+
+// Add shape parameter at top
+shape = "oval"; // or "rectangle"
+
+// Use conditional in base_layer
+module base_layer() {
+    if (shape == "rectangle")
+        rectangle(oval_width + base_offset*2, oval_height + base_offset*2, base_thickness);
+    else
+        oval(oval_width + base_offset*2, oval_height + base_offset*2, base_thickness);
+}
+```
+
+### Add Logo/Icon
+```scad
+// Import SVG or PNG
+module logo() {
+    translate([0, -oval_height/3, base_thickness + top_thickness - text_depth])
+        linear_extrude(height=text_depth)
+            import("logo.svg", center=true);
+}
+
+// Add to top_layer difference
+difference() {
+    // ... existing blue oval
+    logo();  // Cut logo
+}
+```
+
+### Batch Different Sizes
+Modify Python script to pass multiple parameters:
+```python
+cmd = [
+    r'C:\Program Files\OpenSCAD\openscad.exe',
+    '-D', f'name="{escaped_name}"',
+    '-D', f'oval_width={width}',    # Variable width
+    '-D', f'text_size={text_size}', # Variable text size
+    '-o', output_file,
+    template_file
+]
+```
+
+## Troubleshooting Commands
+
+```powershell
+# Check OpenSCAD version
+& "C:\Program Files\OpenSCAD\openscad.exe" --version
+
+# Test SCAD syntax (no output, just validation)
+& "C:\Program Files\OpenSCAD\openscad.exe" --check nameplate_template.scad
+
+# Render with verbose output
+& "C:\Program Files\OpenSCAD\openscad.exe" -D 'name="Test"' -o test.stl nameplate_template.scad --verbose
+
+# List available fonts in OpenSCAD (run in OpenSCAD console)
+# Help → Font List
+```
+
+## 3D Printing Notes
+
+- **Material**: Two colors required (white + blue recommended)
+- **Layer Height**: 0.1-0.2mm for clean text
+- **Infill**: 20-30% sufficient for thin nameplates
+- **Supports**: Not needed (flat design)
+- **Orientation**: Print flat (as modeled)
+- **Bed Adhesion**: Brim or raft recommended for thin parts
+
+## Quick Reference
+
+### Add New Name
+1. Edit `names.txt`, add line with new name
+2. Run `python generate_nameplates.py`
+3. Find STL in `output_stl/` directory
+
+### Change All Dimensions
+1. Edit parameters at top of `nameplate_template.scad`
+2. Run `python generate_nameplates.py` to regenerate all
+3. Or manually test with single name first
+
+### Install Font on New Machine
+1. Copy `Fordscript.ttf` to new machine
+2. Right-click → "Install for all users"
+3. Restart OpenSCAD if running
+4. Test with manual OpenSCAD command

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is a 3D nameplate generator that creates two-layer oval nameplates with engraved text using OpenSCAD. The system batch-processes names from a text file and outputs STL files ready for 3D printing.
+
+## Architecture
+
+**Pipeline:**
+1. Python script (`generate_nameplates.py`) reads names from `names.txt`
+2. For each name, it invokes OpenSCAD CLI with the parametric template
+3. OpenSCAD renders the 3D model using `nameplate_template.scad`
+4. STL files are output to `output_stl/` directory
+
+**Design Structure:**
+- Two-layer design: white base (1.5mm) + blue top layer (1mm)
+- Text is engraved completely through the blue layer to expose white underneath
+- Oval shape created by scaling a cylinder
+- All dimensions parametric for easy customization
+
+## Key Commands
+
+**Generate nameplates:**
+```bash
+python generate_nameplates.py
+```
+
+**Test single nameplate (manual):**
+```bash
+"C:\Program Files\OpenSCAD\openscad.exe" -D "name=\"TestName\"" -o output.stl nameplate_template.scad
+```
+
+## Critical Configuration
+
+**OpenSCAD Path:**
+The script uses hardcoded path: `C:\Program Files\OpenSCAD\openscad.exe`
+Update in `generate_nameplates.py:36` if OpenSCAD is installed elsewhere.
+
+**Font Requirements:**
+- Uses Fordscript font (Fordscript.ttf in project root)
+- Font MUST be installed in Windows (right-click → Install) for OpenSCAD to access it
+- OpenSCAD references fonts by name, not file path
+- Referenced in template as `font="Fordscript"` (line 44)
+
+**Dimensions:**
+Default nameplate size: 3" tall × 8" wide (76mm × 200mm)
+All dimensions in `nameplate_template.scad:6-12`
+
+## File Purposes
+
+- `nameplate_template.scad` - OpenSCAD parametric template defining the 3D geometry
+- `generate_nameplates.py` - Batch processor that calls OpenSCAD for each name
+- `names.txt` - Input file with one name per line
+- `Fordscript.ttf` - Custom cursive font (must be installed in Windows)
+- `output_stl/` - Generated STL files (one per name)
+
+## Modifying Dimensions
+
+Key parameters in `nameplate_template.scad`:
+- `oval_height` - Overall height (currently 76mm = 3 inches)
+- `oval_width` - Overall width (currently 200mm ≈ 8 inches)
+- `base_thickness` - White layer thickness (1.5mm)
+- `top_thickness` - Blue layer thickness (1mm)
+- `text_depth` - Engraving depth (1mm - cuts through entire blue layer)
+- `text_size` - Font size (30mm)
+- `base_offset` - How much white extends beyond blue (2mm)
