A Multi Material Unit (MMU) for eight filaments that can also function as a filament dryer and can keep it dry while printing. The design is heavily inspired by voron and their printers.
A good way too reduce friction could be to have the PTFE tubes go all the way in to the crossing point, printing with nylon might also work since it has a low friction coefficient
We might want to think about including a PTFE tube cutting guide to get a really neat and tight splice of the tube sections.
[ ] Open the cavity to ensure that filament dust can escape, preventing binding or blockages.
[ ] Extend the tubes as far as possible.
[ ] Consider making a jig to cut the PTFE tube so that all four sections align perfectly, ensuring there is no point along the run where the filament comes into contact with the plastic.
