Ender 3 Filament Roller (No Extra Parts)

thingiverse

Remixed from another filament roller to prevent the filament from bending. Since I didn't have a spare wheel bearing or a screw, I decided to modify the design so I could print it without any extra parts. The wheel doesn't have the bearing anymore, but it still rotates freely with very little friction. The screw is also 3D printed. It goes through the holes, and can be pulled back out pretty easily (but not so easily that it'll come out on its own).
