Top mounted PTFE tubeholder for injection spoolholders that came with MMU3.

This is a remix of two models

  1. The PTFE holder clip for the Prusa MMU (PTFE-holder-INJ-R3.stl)
  2. The arm and clip from Vincent Groenhuis's “Universal Auto-Rewind Spool Holder” (https://www.printables.com/model/168-universal-auto-rewind-spool-holder-mm)

I've included two versions. One with the clip on a vertical frame (so the tube is held horizontal) and one with the frame tilted to 30 degrees, slightly behind the spool. This is to allow for different paths of the tube.

Model is broken into two sections due to size and to make printing easier. I've included 3 screw holes for M4x14 or M4x18 bolts and nuts. Use top and bottom holes if mounting straight, or possibly only use middle if you need a different angle than vertical or 30 degrees. 

I printed with PLA, 0.2mm layer height, 25% infill. Used organic supports for the top section (for bolt holes, but don't think they are really needed). Used snug supports for the bottom section.

Any feedback welcome.
