MMU3 STOCK - Filament # indicator!

STOCK MMU3 - Filament # indicator!
Bolt-on "cam-follower" design - flip in/out tag displaying the filament # in use.

Only one part needs to be replaced! The 3mf file is made for MK4 with MMU3.

For the shaft I used one of the aluminum tube supplied with the MMU2S filament spool holder. If you do not have one you can print the one included or any dia 8.0mm x 120mm long shaft/pipe.

A video of the original made for MMU2S WITH the relocated CCA is available below, and describes how it works.
