Lack Enclosure MMU2 PTFE Lower Filament Route

This goes along with my upper PTFE filament route.  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.  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.   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.

I had to reprint this twice, .19" was too tight so I increased the paths to .21".  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.

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.  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.

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.  This has also yet to be tested for operation, but it should work just the same.

Again… only partially tested, so who knows if it will work well.
