Prusa i3 MK2 Multi Material - Extruder motor mount with increased tilt
thingiverse
I found the existing tilt of the standard prusa multi material extruder motor assembly not sufficient to provide clearence between the ingoing filaments and the outgoing cables of the extruder carriage (especially after I installed the PTFE tube adapters https://www.thingiverse.com/thing:2577668, which you can see in the pictures above). Therefore I changed the angle of the assembly mounts from 30 to 70 degrees. In consequence the filament does not protrude into the build volume and maintains sufficient clearence to the extruder carriage. This remix of the standard prusa mount could also be interesting, if you plan to install your filaments above your printer and therefore want to guide the filament outside the top side of an enclosure.
