Filament Roll holder

thingiverse

I have designed this for Flsun Cube, and it's compatible with the stock filament holder, making it a great upgrade option. I've utilized two 6202 bearings, but smaller ones could also work well. One thing that stood out to me was that on the stock filament holder, rolls heavier than 250g tend to get stuck, causing the extruder motor to struggle and overwork itself as it tries to pull the filament through. However, with this design in place, I've added two bearings, which have made a significant difference – you can even see the filament roll back to its starting position when the extruder motor retracts it during printing. This design is versatile and works well with rolls of any width. I'll be continuing to refine and update this design soon.
