Ender 3 Filament Guide - Slotted for easy install

thingiverse

This is a remix that has slotted holes for easy installation. Loosen the screws, and slide this in. Make sure the spring washers are seated ABOVE the printed part. This filament guide should fit flush against the Z axis stepper motor mount for the ender 3. The goal is to prevent the filament from touching the z-axis lead screw and therefore collecting grease. I've found it works quite well. I added the .step file if you wish to make further changes. Tapering+chamfering the slot might help with assembly, although I had no issues using an o-ring pick to raise the washer and slide this underneath.
