Refill Spool v3 (180mm Prints on A1 Mini)

Welcome to the 3rd revision of the refill spool! Thanks for all the feedback that's made this an even better spool!

✅ Compatibility:

• AMS Lite Compatible (200mm version for the AMS here)
• Filaments:
  • Bambu Lab Refill Spools
  • Polymaker Refill Spools
  • Any standard cardboard core refill (82mm ID, 60mm width)

🚀 Key Features:

• Super Lightweight: Only 73g of PLA/PETG, or 60g of ABS. Compared to 130g+ for other spools
• Space Saver: When not in use, you can stack 4 of these in the space of just 1 regular spool
• Smart Design:
  • "No-kink" filament retention system
  • Easy swap system using filament straps
  • Integrated Bolt Design: Includes backup holes (Note: The bolts are designed to bottom out—don't overtighten!)
• Swappable Labels: Label your spools clearly! Swap them out whenever you change filament. Includes a customizable model to create your own text labels
• NFC Tag Support:
  • Reuse old Bambu Lab Filament NFC tags on other brands for auto-read
  • Support for 20 and 25mm NFC stickers for inventory tracking
  • An alternate “Side 1” compatible with OpenPrintTag
• Optional Desiccant Core: Keep your filament dry right on the spool

📝 Printing & Notes:

• Material: I highly recommend printing in PETG or ABS if you plan to use this in a filament dryer (PLA might warp!)
• Tools: Includes a printable tool, or use a flat-head screwdriver
• Print Settings: 0.4mm nozzle, 0.2mm standard layer height (recommended: 0.15mm layer height for the thread sections)
