Lack Enclosure MMU2 PTFE Lower Filament Route

<p>This goes along with my upper PTFE filament route. &nbsp;I want to use the filament dryers in the bottom cabinet, so I made a way for the PTFE to pass through the acrylic and stay neat and orderly. &nbsp;I caused the bottom to fan out a bit so I'm hoping that it will work with 5 filament dryers in the bottom cabinet, though this has yet to be tested. &nbsp; The idea is the filament will free float between the dryers and the PTFE route, and I don't think I will need a buffer… although the print I'm doing now DID kink and I had to bend it back before it got sucked up in… so your mileage may vary.</p><p>I had to reprint this twice, .19" was too tight so I increased the paths to .21". &nbsp;Now it's pressed up against the ½" hole too tight on the outside two routes so I need to open those holes up more.</p><p>Make sure you don't cut your PTFE tube too short so it doesn't stick out… I did that so now I am making a PTFE coupler so I can cut the tube and fix it. &nbsp;It was such a pain to put the PTFE in the MMU2 so I'd rather leave that attached, cut the tube, and extend it.</p><p>I put threads in the bottom for M3 screws to press into the PTFE tube like Prusa did with the filament buffer on the MMU2. &nbsp;This has also yet to be tested for operation, but it should work just the same.</p><p>Again… only partially tested, so who knows if it will work well.</p>
