Filament Guide

I created this filament guide as I found other filament guides had some issues I wanted to fix.
1. I wanted the model to be completely printable. (no bearings) I found that the bearings in other filament runners didn't even spin, so why have them.
2. When the extruder would move to the left, I found that the filament guide would get pushed out of it's mounting hole, so I added a twist nob to lock it in place.
3. My final reason for making this design was that I wanted it to print in one piece.

Installation:
1. Remove the rafts if you used them.
2. Twist the nob to break free any connections that may have formed.
3. Press the filament guide (you may need to use a fair bit of force) into the hexagon hole.
4. Reach under and twist the nob just slightly to lock the filament guide in place.
