Mini Splitter v2 for MMU2+1s mod - PC4-01 fitting version

This is a remix of Mini Splitter v2 for MMU2+1s mod adapted to use PC4-01 fitting between the splitter and the extruder.

The idea of this mod is to releive the tension in X carriage caused by 10 PTFE tubes connected directly to the extruder.

You will have to print both parts.

1. Splitter. It's the version dessigned for FDM. Print the file as it's been uploaded, that is, with the 10 holes facing the bed. No supports needed. 3 perimeters. Infill 15%. Recommended to print with low layer height (0.15 or lower) so the interior of the splitter is as smooth as possible.
2. fs-cover. Same print settings as original file from Prusa.

You will need a PTFE tube to join both parts. Recommeded length 70mm. Recommended 2,5/4 PTFE (inner/outter diameter) making a chamfer in both ends.

You can get MMU board firmware here:

The rest it's the same as in the original version https://www.prusaprinters.org/prints/71799-mini-splitter-v2-for-mmu21s-mod. Needed set screw M3x3mm or larger to fix the PTFE to the splitter (one per PTFE, max. 10)
