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)

📊 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
