Multi-Material Test Block I created this small test block (50mm x 10mm x 6mm) to debug my Prusa MK3S MMU2 setup. In addition this test block allows me to evaluate the color bleed of the filaments. You will see in this print that the red (block 1) bled into the white (block 2) making it pink. I will need to extend the wipe length for the white filament in the slicer.

Each block corresponds to my 5 filaments and because the we cycle through all 5 filaments for ever print layer, the wipe tower is 5 times larger than the object being printed.
