Microscope Camera Distance

When I switched out the camera on my trinocular microscope I had the problem that it was hard to focus the eye pieces and the camera at the same time. Focusing both at the same time was possible, but just at the limit of the adjustment knob. Problem turned out to be simple, the distance of the camera to the camera mount was too short. I designed a simple distance that moves up the camera 7mm and that moved the focus to the halfway point instead.

The hole in the side is designed to be threaded with a M3 thread tap for a captive screw.

I have also attached the design file for Fusion360 in case your setup needs a different distance.
