Prusa MMU2(S) Easy Selector Maintenance Mod

thingiverse

This modification makes maintenance of the filament selector for the MMU2(S) significantly simpler. To detach the selector, one must still remove the screws securing the selector's stepper motor in place, but removing the selector rails from either side should simplify this process. Two M3x8mm screws can be used to secure the two 5mm rods that the selector rides on, as shown in the illustration. The pictured part was printed using Novamaker Green PETG. Edit: A design flaw affecting printability has been identified in the original model's right side next to the selector stepper. The revised version should print more smoothly with a minimal ~13mm bridge required. Updated STL and STEP files are now available.
