Filament guide

This is a filament roller guide. It uses one 608zz (8x22x7) bearing. I designed the wheel in two pieces for easier printing with no supports and for easier bearing insertion. once the wheel halves are pressed onto the bearing you will never know its two pieces. Put a shim on each side of the bearing on bolt (axle). print bolt and nut at .16 with 100% infill. Adjust nut to 111% on the X and Y axis only.

Works with spool holder:
