Leadscrew/filament guard/guide for Ender 3 / Pro. FreeCAD file included
Description
A small accessory that fits over the ender3's leadscrew. It prevents the filament from touching the leadscrew and picking up foreign matter like grease, oil, metal particles, etc. I'd use a low-friction material such as nylon and a relatively low layer height (<0.16mm). Thick walls and high infill percentages are not advised, as these settings often cause warping with chunky models like this. Examine the slicing solution to make sure that it has resolved a solid wall between the filament guide and the hole for the leadscrew. As a general disclaimer: This part does not cause any binding or other problems on my machine, but I make no guarantees. One should use caution in fitting any new part to a machine.
