Prusa Mk3 Filament Guide

This filament guide clips onto the dual filament holder that comes with the Mk3. Provides a nice stable feed of the filament to the extruder, and it also gives you a way of temporarily holding onto the filament during swaps.

Prints with no supports.

EDIT: Added a "v2" version incorporating some suggested improvements. V2 is wider and includes a diagonal slit in each side so you can remove or add the filament without unloading it from the extruder.

EDIT: Some folks reported trouble printing the original due to the bevel at the bottom. It prints fine on my printer but if your printer isn't set up as tight you might have issues. I've added a "v2_flat" version which has 1mm shaved off of either side to assist in printing.

EDIT: Added a "v3" version which has a curved cutout instead of angled straight. I found that sometimes the filament could get itself worked out of the guide with the straight cutout. This one is also "flat" to avoid any bed adhesion issues.
