Camera Mount
I wanted to monitor my 3D printer remotely and take some timelapse photos of prints in operation so I purchased a raspberry Pi camera, because it was an easy way to tie in with Octoprint and I printed myself a camera mount while I waited for the camera to arrive. While I was trying to fit the ball into the socket the whole thing snapped in two (my socket hadn't printed perfectly). The camera I received had a large lens on it that didn't fit into the gap in the housing, so I didn't bother reprinting it to find out whether it was the design or my printer at fault.
