CR-10 Direct Drive Filament Guide

Last crawled date: 4 years, 4 months ago

These parts are assembled to form a filament guide for the CR-10 with a direct drive extruder. I use the direct drive kits found at https://printermods.com/
Although I love the upgrade from a Boden, I am not crazy about putting so much weight on a moving carriage with an unsupported frame such as a CR-10. I definitely do not want to mount the weight of a spool as well. Most direct drive extruder feed from the top so the filament either needs a guide tube or it needs to be pulled from above. My spool is still on top of the control box but it loops up and over this guide to be directed vertically downward into the direct drive.
A standard skate bearing is inserted into the pulley, the printed washer is placed on the bearing with the partially exposed side, then this assembly is inserted into the frame with the washer facing the backside. The axle is a 3/8" bolt with a lock washer or coupler.
