Ender 3 Roller Track Filament Guide

thingiverse

I really liked the look of the design by Holspeed but I didn't have any bearings on hand however, I had just replaced the roller track bearings in my glass sliding doors so used the spare from that. Glass sliding doors generally have very heavy duty bearings (support the weight of the door) and the plastic for the roller is made from Delrin (Polyoxymethylene) I personally am very happy with the result. The bearing just clips in place which also means it can be easily removed if required. I'm not sure if these bearings are available globally? I live in Australia where these bearings appear to be commonplace and can be bought from Bunnings (hardware store) among other places.
