The file 'Ender 3 Filament Roller Guide W/ Retaining Pin 3D Printer Model' is (stl,STL) file type, size is 141.6KB.
This uses the exact same files and methods as the original created by Holspeed except for one difference. I created a file for a pin to retain the roller, bearing, and spacers in the bracket. Holspeed uses an M4 x 16mm bolt that came with the printer. I attempted this but, the bearing kept turning so the screw wouldn't progress further into the spacers. To circumvent this I created a small 16mm pin that I pressure fit into the hole and it works great!
