I used a Raspberry Pi 3 Model A+. The frame is made with Makerbeam, 4x vertical 66mm beams and 8x horizontal 54mm beams.

Raspberry Pi camera mount 3D printed from Shapeways.

DWG CAD files are in hardware/cad-files or you can see models here on Spaceways:

The camera mount supports both the V1 and V2 camera modules.
