Lack Enclosure MMU2 PTFE Upper Filament Route

prusaprinters

<p>I wanted a way to keep the PTFE tubes off the MMU2 to be organized and not kink as they passed through the acrylic in my Lack Enclosure. &nbsp;I designed this originally with .17" diameter, but it was way too tight, so I increased the diameter to .19" and it seems to be working quite well. &nbsp;I tried to design it such that it would still allow a full 8" clearance for a model being printed, and it seems to work. &nbsp;It's short enough that if the machine is all the way forward and just barely touching the doors of the enclosure that the y axis can go all the way back and not hit. &nbsp;I have yet to test it, but it came out well and is keeping the PTFE organized and cleanly routed. &nbsp;I've printed several prints with it in place and the MMU2 seems to have no trouble.</p><p>I used M3 screws and nuts and they worked quite well to hold it in place. &nbsp;The holes in the acrylic are ½".</p>
