PRUSA MMU2 Wall mount spool holder

Wall mount spool holder with five individual threaded shafts and tapered nuts that can accept most commons spools for easy replacement, a 2 axis filament guide in which the PTFE tube can be firmly inserted, designed for the MMU2 upgrade.

I designed two threaded mainshaft, with or without bearings, for the bearing version you need HK1012 needle rollers and rectified steel rod.
