# 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
