Ender 3 Pro Filament Roller
thingiverse
Filament Roller, custom fit to the already existing Ender 3 Pro filament Holder. Bearings are placed around the roller and then snapped into the holder. The screw is a bit tight, scaling the x and y before printing could help, but I just filed it down to make sure the fit was still tight. Very solid and reduces the scraping noises from the filament rolls
