Remix of the camera arm here: https://www.thingiverse.com/thing:4487566/remixes
This model supports the ArduCAM (OV5647) Pi-compatible camera module— specifically the one with the 160deg FOV lens. I also added some gussets to the arm ball-socket because the original snapped as I was pushing the ball in. This one is a little stronger and has a little more material to hopefully prevent that.
