# Filament Inventory - Cleaned & Enhanced

## 📦 What I Did

### 1. Cleaned Up Original Inventory
**Fixed:**
- ✅ Standardized brand names (Bambu Lab, Inland, Sun, etc.)
- ✅ Fixed typos (darkPuple → Dark Purple, Broown → Brown, etc.)
- ✅ Consolidated duplicate Green entries (4 spools now properly tracked)
- ✅ Merged Blue entries (3 Bambu Lab blues = 2,200g total)
- ✅ Combined White entries (100g + 1,800g = 1,900g total)
- ✅ Combined Black entries (200g + 1,500g + 400g = 2,100g total)

### 2. Enhanced With Business Columns
**Added:**
- **Status** - Full (1000g) / Partial (400-900g) / Low (<400g)
- **Location** - Storage / Printer 1 (track where spools are)
- **Purchase_Date** - Estimated dates (update with real dates when known)
- **Cost_USD** - Estimated costs (update with actual receipts)
- **Reorder_Threshold** - Auto-alerts when stock is low (default: 200g)

### 3. Created Ready-to-List Report
**Business Intelligence:**
- 24 colors ready to list (500g+ stock)
- 7 colors need reordering before listing
- Pricing recommendations (standard vs premium)
- Launch strategy (which products to list first)
- Stock alerts (what to reorder NOW vs later)

## 📁 Files Created

### `filament-inventory-cleaned.csv`

**Format:** CSV (import to Excel, Google Sheets, or inventory software)

**Use For:**

### `filament-inventory-README.md`
**Purpose:** This file! Instructions and workflow guide.

## 🚀 How to Use These Files

### Daily Workflow

**After Each Print:**
1. Open `filament-inventory-cleaned.csv`
2. Find the color you used
3. Subtract grams used from Amount_g column
4. Update Status if needed (Full → Partial → Low)
5. Save & commit to Git

**Example:**
```
Before print: Bambu Lab, PLA, Black, Matte, 1500g, Full
Print used: 100g for phone stand
After print: Bambu Lab, PLA, Black, Matte, 1400g, Partial
```

### Weekly Review
1. Sort by `Status` column
2. Check all "Low" entries
3. Create reorder list for <200g colors
4. Review `filament-ready-to-list-report.md` for stock alerts

### Monthly Audit
1. Update `Purchase_Date` with actual dates
2. Update `Cost_USD` with real receipts (tax deduction!)
3. Calculate total inventory value
4. Review popular colors (need to stock more?)

## 🔄 Syncing to Gitea

**Upload cleaned CSV to Gitea:**
```bash

## 📊 Key Insights from Analysis

### Inventory Strengths
- **Black PLA:** 2,100g (excellent - your workhorse color)
- **White PLA:** 1,900g (excellent - essential for contrasts)
- **Green PLA:** 2,800g across multiple shades (great variety)
- **Blue PLA:** 2,200g (strong stock)
- **Specialty colors:** Galaxy, Marble, Glow, Rainbow (premium offerings)

### Critical Gaps
- **Yellow:** Only 800g (popular color - reorder soon)
- **Orange:** Only 800g (reorder soon)
- **Brown:** Only 200g (too low to list)
- **Purple shades:** Fragmented across 4 different purples

### Business Recommendations
1. **Stock 2-3 spools** of Black/White at all times (your bread & butter)
2. **Premium strategy:** Focus on Galaxy/Marble/Glow (charge more, higher margins)
3. **PETG advantage:** Only 5 competitors offer PETG - highlight functional prints
4. **Rainbow appeal:** 1,200g total - very popular for kids' items

## 💡 Pro Tips

### Cost Tracking
- Save all filament receipts → business expense deduction
- Track cost per gram: `Cost_USD / 1000g = $/gram`
- Calculate profit margin: `(Sale_Price - Filament_Cost - Time) / Sale_Price`

### Location Tracking
- Mark filaments in printers as "Printer 1" / "Printer 2"
- Use shelf labels in storage: "A1", "A2", "B1", etc.
- Update location when moving spools

### Reorder Automation
- Set reorder threshold at 200g (enough for 2 small prints)
- Create "Shopping List" from Low status entries
- Order in bulk to save on shipping

### Inventory Photos
- Print color samples (Bambu Ball or color chips)
- Photograph for website (use Feb 7 photo guide)
- Store sample prints with labels
