Solving My Only MMU3 Problem For The Prusa Core One

Published at : 23 Dec 2025

If you're a Prusa MMU3 owner, you know that the space required to set it up can be a pain and a waste. Today I am using the community build of the MMU3 on the Prusa Core One so that I can create a more compact version of it by integrating it on the top of the machine and using the same footprint.
