BB Pellet Filament Roller

BB Pellet Filament Roller

thingiverse

I designed filament roller with bearing using BB pellets for Elegoo Neptune 2s. 20 balls are installed in one place without retainer. Since the attached filament holder is used, it is necessary to avoid the flange and the radial gap is quite large. The overhang angle is set to 50 degree. The flange diameter is assumed to be 32mm, the shaft diameter to be 30mm, and the length to be 87mm.
