Creality Ender 3 Filament Guide Roller

thingiverse

This was used as a filament guide for my Ender 3. This part was created to prevent the filament from rubbing on the inlet to the extruder and creating a wear spot. I had a spare 22mm OD, 8mm ID, 7mm wide skate bearing that worked nicely for the rolling element. If the slot is too loose, apply tape to the metal flange on the printer until it fits snug. All designed using Fusion 360.
