Ender 3 Z Axis Bearing support and Filament Guide

thingiverse

Here ya go! Plenty of Z support prints and filament guides caught my eye, but I wanted something that did both. So, I came up with this! I left the bearing at a slightly lower height to make way for a z-axis adjustment knob. Be aware, though - I haven't checked for interference from the x-gantry at max height, since I never print anything that goes that high. Print this in a similar orientation as seen in the screenshot. For supports, just use "Touching build plate only". Around 10% infill is about right, depending on your chosen infill style. The bearing used is the standard 608 (8x22x7mm) model and should fit snugly with some pressure. The hardware I used came spare with my Ender 3 - a couple of extrusion locking t-pieces and M4x14 countersunk bolts. Anything similar in size should work just fine. I think that covers everything. If you have any questions, leave a comment!
