Prusa MMU Filament Guide

thingiverse

I ran into the same problem others have with my filament rolls on top of my Lack table enclosure feeding filament into the Prusa MMU2S filament buffer - the outside filaments were getting caught on the little notches that Prusa puts into their filament rolls. I love @HikerGlenn's simple design, but I didn't want to eject all of the filaments I already have in the machine - so I made a simple cut into the ring so you can install these guides on the enclosure for filaments that are already loaded. Just make sure to keep the opening in the ring facing the *outside* of the filament row (away from the center of the filament buffer)...
