This is a remix of: https://www.prusaprinters.org/prints/22339
Made for M10 (1.0 mm pitch) passthrough couplings (since that's all i have) that allows for the PTFE tube to be pushed all the way in to the MMU2S body and hence does not require any transitional PTFE tube. You need to push the PTFE tube all the way in, you will feel a slight increase of force required the last couple of millimeters.
Printed in Prusament PETG, 0.2 mm layer height, 20% infill.
These are the couplings that i used: https://www.amazon.se/-/en/gp/product/B07SKX5P9P/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
