MMU2 Tension Screw Keeper

thingiverse

Assembling my MMU2 was an exercise in frustration, as I quickly discovered that one of the first challenges is keeping the screws from falling out when opening up the assembly to access the filaments. It's a miracle I didn't lose one of the springs. To rectify this issue, I took matters into my own hands and modified Prusa's control board cover to include an extended keeper for the screws. The design allows for easy adjustment of the screws while still enabling full opening of the head without worrying about them falling out. What's more, the control board cover can be removed in its entirety to facilitate full removal of the screw.
