Filament Roller and Guide for CR10 (2020, 2040... - profile)

thingiverse

I built my own filament rollers, brackets, and guides because none of them met my expectations. It's not rocket science, after all. You'll need two 628Z bearings for the roller, two t-nuts or hammer nuts, and screws to hold the bracket together, as well as a M3x18 screw and nut to secure the guide in place. Print the roller vertically with support material and consider adding brim for better adhesion, especially if you're printing it without supports. The same goes for the guide; you might want to add brim there too. Make sure your models are set up in print orientation before sending them to the printer.
