Microsoft LifeCam Studio microscope adapter astro cam
Microsoft LifeCam Studio to microscope / astrocam conversion kit Barebone version

NOW updated with the holder for the camera with original casing so you can plug your Microsoft livecam studio directly into the printed holder and mount to the Leitz microscope camera port. liveCamShellBarebone v20.stl

Microsoft LifeCam Studio is an awesome small cam. I was able to get rid of every unnecessary part, file down the PCB and fit it into the eyepiece of my old Leitz microscope eyepiece. The eyepiece diameter is 23.2mm and my camera fits nice and snug.
So there is a printed camera housing,
a set of adapters that allow to place the camera into the camera port of the microscope that has a diameter of 35.4mm
The camera port assembly allows the smooth focus adjustment.

I will include the 3mf files so you can modify the parts to your needs.

I printed all parts without any suports , except for the one part that sits on top of the camera port on the leitz microscope. You can see the placement of this part on the screenshot, where the supports are marked with bright green in the prusa slicer.
