Note:1,The kit doesn't include the printed parts, you have to print them yourself.
2, The printer and filaments aren't included in the kit!

This is the result of several months of designing and testing new ideas for increasing the filament count of the Prusa MMU2S. (And then more testing and re-designs for the MMU3.) I tried several variations, but ended up coming back to something that is largely based on the original Prusa model. Some of the major adjustments include:

• increased filament count from 5 to 12

• reversed position of pulley and idler motors, to maximize the use of the 110mm pulley shaft

• moved FINDA to the rear of the selector, in an attempt to minimize issues where the filament clears the ball but then still fails to fully retract

• quick-release insert for FINDA sensor, for ability to clean or check ball chamber without re-calibration of FINDA height

• selector has integrated threads for PTFE quick-connect

• moved control board beneath the body (inspiration thanks to univeraljoint)

• additional bracket mounting options

• selector does not include the cutter

As of October 2024, this project has been updated to include the MMU3 with the Mk4. New features now also include:

• a new idler alignment gauge of the front side of the upper frame

• a streamlined idler design

• a smaller inlet that uses the PTFE collets instead of M10 screw connectors

• a cover panel for the power connection board
