Ender 3 Filament Guide (with Cutout)

thingiverse

### Info This is a remix of a very handy little filament guide for the Ender 3. I did this for my Ender 3 V2 and decided to add a little slot to the ring that allows you to just clip in the filament while it's already fed into the extuder. ### Original Description Here's the original description from MattEllison: Here’s my take on solving the filament path / tension issue on my Ender 3. I noticed that some of my prints had diagonal lines on the top layers as the extruder was struggling to pull filament into the feed hole at a consistent pace. When there was tension, I got 10% or 15% under extrusion. I came up with this design to address problems I found in mounting the other “2020” filament guide on my X gantry. The bungs broke almost immediately since I printed the parts in PLA. This version slides over the top of your spool holder (the metal part). Just un-screw one of the “nuts” holding the roller to the metal piece and slide this guide over top. It should be a tight fit, which keeps it from wobbling around. The straight part should rest on the top of your frame, making for a much smaller profile piece. This part works great with an extruder intake guide like this one: https://www.thingiverse.com/thing:2873157
