Changes from 3dxl KK2.0 case design:
1) Flipped the case upside down because I did not want to print supports. Unfortunately you loose the little notches on the buttons, but I found I could still press them easily.
2) Changed the clipping and swivel of the case on the base to a screw fit. I used #6 bolts from Home Depot.
3) Changed the screw layout on the base to fit this design: http://www.thingiverse.com/thing:32281
4) Added holes for the KK2.1 board buzzer and battery power port on the case.
