This is a remix of the Filament Roller Guide by Holspeed.
* 3-26-22 Update: Edited mount to better lock into place so it does not shift anymore.
Their guide was a great idea but it did not line up with the extruder great on my Ender 3 v2 and I also wanted to use a 6000 bearing I already had laying around so I modified their design a bit.
The parts you need are 6000 bearing and M3 bolt with either a matching nut for the backside or in my case I used a heat set insert.

6000 Bearing: https://www.mcmaster.com/5972K81/
M3 bolt: https://www.mcmaster.com/92095A472/
The mount just slides over the frame where the stepper motor attaches and is held in place with a friction fit. The bearing is also a friction fit for the pulley wheel. The mount has steps where the inner race on the bearing sits so you can tighten the bolt without binding the bearing.
