New: I just did a blog post on my enclosure-related MMU2 mods:
A challenge of the MMU design for those of us who use enclosures is that the lights are not visible without a view of the top of the unit.
This control box moves the control board to a better location that is both easier to see and easier to access. There are no modifications required to the MMU pulley assembly or frame holders for this design. Please note that you will need to substitute longer screws as follows:
3pc M3 X 12mm machine screws to secure the MMU controller board
3pc M3 hex nuts (you can reuse the nuts from the original MMU controller cover)
4pc M3 X 30mm machine screws to attach the frame holders to their original mounting holes through this unit.
-slight increase to clearance on left and right side of cable plug region.
4 perimeters and 4 top and bottom layers.
