Ender 3 V2 Filament Guide

This Filament Guide is the first thing I created start to finish. It ain't pretty but it works well.

I wanted something that would use a wheel and have minimum drag on the filament, while guiding it straight into the extruder. I designed it to use no hardware to assemble or mount it on the printer. It has a friction fit and is easy to remove to gain access to the extruder. The Z stepper motor gets warm so there are plenty of cooling vents.
