R3D Bambu Compatible Reusable Master Spool

The R3D Bambu Compatible Reusable Master Spool lets you print from refill coils without buying a new plastic spool each time. It's designed to work in Bambu AMS setups, and a locking mechanism keeps the coil tightly wound so it feeds smoothly.

• Reusable, cutting plastic waste and long-term filament costs
