Reusable cardboard spool (AMS lite compatible)

If you have empty cardboard spools lying around, why not put them to good use? This 3D-printable adapter allows you to convert a cardboard spool into a reusable spool for Bambu refill filament. The pictures show the simple process of dissasembling the cardboard spool using your bedscraper or another sharp object, and then reassembling with the 3D printed refill adaptor. Features: ✅ Designed to fit ESUN cardboard spools (other brands might work) ✅ Compatible with Bambu refill filament ✅ Easy to print—no supports needed ✅ Campatible with AMS lite This is a great way to reduce waste and save money by reusing old spools instead of buying new ones, or printing the whole spool. Let me know if you have any suggestions for improvements!
