Bed camera mount for Makergear M2

This is a bed camera mount for the Makergear M2. I designed it, originally, to use with a Raspberry Pi camera inside this case: http://www.thingiverse.com/thing:1646474 . I redesigned it to be a little more general by using a tripod-screw mount with a threaded ball mount for the Pi camera case. Now, you can use it with any camera with a tripod mount. Still, you'd be better off using the low-mass Pi camera.

If you're careful, you can mount the camera directly on the bed mount. That's the way I did it. For a while. Then I was rudely reminded that the part-cooling fan may smash into whatever you mount there should your printer move the hot end out near Z0,Y0,X200. The quickly-designed extension arm will help keep the camera out of harms' way. It has serrations to match the bed mount and will lock the camera at your selected position.

To install the camera mount, you will need to remove the rubber corner piece (shown sitting on the bed in one of the photos. Save it somewher
