MMU2 Buffer Sidefeeder (for LACK Enclosure V2)

To feed  filament into the mounted buffer to the MMU2 without removing or reconnecting the already connected tubes.

You need 5 short PTFE tubes (around 7cm each) and 10 PC4-M10 connectors. I use ID 2mm PTFE for the short part (most of my other PTFE are ID2.5mm) because you want some friction in that part to prevent the filament being pushed out of the buffer. For the same reason you should adjust the angle the feeders are mounted on the enclosure to make sure the filament ist not pushed back. Just load to nozzle and then unload the filament to check before you fix the feeder in place. If you mount the feeders similar to the way on the photo it should work nicely. Be aware that depending on where you fix the feeders you might end up above the cut-out in the enclosure V2 top (like I did). In this case using a short screw and nut is better than a normal screw.
