So after getting everything working (repeatability!) I moved to making it pretty :)
I used this design for my lcd controller board and added a custom holder (can be found in the files section) so it fits the screw holes of the Replicator 2(sorry K :).
Next up an adapter for the RAMPS/Arduino board.
Mount adapter for Replicator K (hot glued):
Old LCD vs new LCD:
And fully assembled:
(I had to cut the MDF panel, it wasn't a clean cut but I don't care since I plan to replace the panels anyway).
