This is a device to mount a Microsoft lifecam HD-5000 to the eyepiece of a microscope. It includes six adjustment screws to allow for perfect alignment.

I used springs between the CameraMountTop and CameraMountBottom so the camera can be tilted using the three adjustment screws.

You need three 12 mm long 3mm diameter machine screws, and four 8 mm long ones, and three compression springs.

Should fit on most microscope eyepieces... Although be warned it's a bit of a tight fit. I guess you can make the CameraMountBottom scaled up a bit to solve that issue.
