Case with support for 7 inch capacitive touch screen (SKU:101-40-192 | UPC:6959011562004). This screen connects via HDMI and has an USB connection for power and touchscreen functionality. It attaches using bolts and nuts, including 2 x M3-30mm, 4x M3-16mm, 1x M4-40mm, 6 x M3 nuts, and 1 x M4 nut. Additionally, it uses a 15x15 mm alu square profile for the arm that attaches to the wall. You have access to the FreeCAD source code. Use FreeCAD version 0.17 (it uses Part Design NEXT). Be aware that my printed version was 1 mm too short and I had to rework the PCB by increasing the holes to 5 mm. This issue has been resolved in FreeCAD, but this design remains untested. If your PCB holes do not align properly after printing, drill out the touchscreen PCB holes to 5 mm. You may also want to consider modifying the resistors that regulate screen intensity to 2 resistors of 20 ohms, as the stock ones (1 ohm in parallel with 2 ohms) are too bright. For further optimization, you might find this hack helpful: http://capnbry.net/blog/?p=210. In the hack, you can see the two resistors I recommend replacing with your own.
