This is my camera mount for original Prusa i3 printer. I have M12 lens adapter on camera, so I have to modify the cover. Fits on Raspberry camera v1.3, does not fit on v2 camera.
I also designed new arm connected directly to heatbed frame, no need to take off the camera when I want to change glass.
1x M3x40 hex head (ISO 4017)
3x M3 nut
Rotating part has integrated M4 nut, so you have to add pause to gcode (or use prusa color change software without changing color).
I have heatbed lifted by bearings mount (http://www.thingiverse.com/thing:710913), wihout this, arm will colide with display cover!
