This is a case for the Intel Edison with the Arduino Expander Board. The slots allow access to Arduino shields. All edge I/O are accessible.
I've included guides for control of the 5 on-board switches using separately printed switch extenders (I'll add the STL once I get the geometries optimized). Also included are holes intended for light-pipes for on-board LED's using a material like T-Glase or some other transparent/translucent material (STL in progress).
Update: I've uploaded the switch extensions. These allow you to operate all 5 board switches.
Print the case. Remove the tabs. Insert Edison and Arduino Expansion board. Secure with 4 screws inserted through the bottom of the case.
