Wanted to mount my internet cam to the bed rather than being static on the rail so came up with this remix. works great and also makes a really nice handle form moving the Y axis.

There is a right and left-hand version included, I mount them both and use the one that doesn't have the camera as a handle. The left-hand version is slightly different because it was first and I revised the right hand somewhat, but they both work. I was just too lazy to upgrade the test to the final design.

The final design has the bed screw run through a hole, the original test was a slot that slides on and around the bed screw. I also added a slot for a zip tie, but it's unnecessary. 

The base is specific to my camera as linked below. I dismantled the provided base to get to the simple attachment point I designed. It's quite easy. It uses the same hardware.
