Although the lite version of the MMU3 mounting brackets gets the job done, it requires the mounts to be clipped on the lip of the metal top rail. This design prevents the use of the top acrylic panel and interferes with proper chamber heating. I also didn’t like the angle of the MMU after the install so I designed this with a 35deg back angle from horizontal. This is fully compatible with the PRUSA air filter and mounts with two m3 screws inserted through the top back rail. I recommend washers on the m3 screws as the MMU is heavy for only two screws to support it.
In order to use the MMU3 with the Core One, you have to modify the nextruder. Here are the steps from Prusa https://help.prusa3d.com/guide/9d-core-one-nextruder-mod_111779
Also, check out my pass-through mod for the top panel if you plan on keeping it in place like I did. https://www.printables.com/model/1383020-mmu3-core-one-top-panel-ptfe-passthrough
