Ender 3 - Filament Roller Guide

I only had M3 x 20mm hardware available, so I modified the knob to work with that size. I also added some holes to the knob for artistic flare. Make sure your tolerances are dialed in. I had to increase my horizontal expansion by .1mm in Cura for the roller. I also needed to use a washer between the bearing and the body piece to get it to move smoothly.
