Gapped Ender 3 Filament Guide

This is a slightly modified version of Matt Ellison's Ender 3 filament guide. I added a gap to the ring to make loading and unloading filament a little easier. I made no other changes to the original.

The gap was sized to accommodate 1.75mm filament.

This is a great design. It works much better than the other clip-on version everyone seems to be using.
