About this 3D model
This is my construction for a RaspberryPi with a PiCam (running Octoprint). Both long arms fits at the back of the Makergear M2 frame. Short and long arms are connected with the connection pins. The RaspberryPi holder fits between the short arms. RaspberryPi circuitboard fits in http://www.thingiverse.com/thing:48085. Make a slot in the case for the PiCam flatcable and glue the PiCam holder http://www.thingiverse.com/thing:189420 on the case 31-12-2013: Updated RPH.stl for better powecable clips 05-07-2015: Timelapse, to give you an idea how it looks like http://1drv.ms/1KEaz4R
