If you keep your spools on a wall-shelf or desk edge with the PTFE tubes running downward from the spools (like I do), this remix is designed for you.
Since setting up my MMU3, I wasn't satisfied the flow of the filament. The angles put unnecessary strain/tension on the filament which could lead to feeding issues or even filament breaking. In my setup, the filament came counter-clockwise off the spool, clockwise down the PTFE tube, then counter-clockwise again right before entering the MMU3. It seemed like too much tension. With these new holders, the filament now flows in a clockwise path until it gets to the MMU3 which dramatically reduces stress on the filament.
I used Blender to redesign the original PTFE holders, adjusting the directional flow from horizontal to VERTICAL and extending the length to line up with a full spool. I printed mine in PLA (because that's all I have).
Once again, whether your spools are on a high shelf or you're just feeding the filament downward to your MMU3, these holders should make your setup a little smoother and more reliable.
