Remix of the "Case for the Full Graphic Smart LCD Controller" (http://www.thingiverse.com/thing:87250), with the mount replaced by one suitable for the K8200/3Drag I designed myself. The encoder knob which was not manifold has been fixed with netfabb.

I'll try to post a connection diagram between the 2 10-pin connectors and the single 18-pin one on the K8200's controller at some point.

Screws for my K8200 mount are M3x16 for attaching the case to the holder, and M4x40 for the clamp. I used 8 3x12 self-tapping screws for the rest.
I recommend using the bottom plate with nut holders.
