Camera mount C, M12, M42

Three screw mounts in one!!

I've made it to attach a c-mount cameras to a M42tube (male), while using s-mount (M12) lenses.
Posted also the T2 (42 x 0,75 mm) screw.

It is made of two pieces. The camera is rotatable (you can tighten it at the angle you want)

I use it for afocal photography with the microscope.
To use it:
1- screw in the M12 lens to "open" the thread
2 - put the flange on
3 - screw in the c-mount camera
4 - fasten the flange to a m42 male screw


The M42 and M12 screws usually come out good; the c-mount instead is a bit delicate and tend to marr if not treated with reverence. No idea why.
Print them it with small layer height (0,1mm) because of the tiny screw threads.
The tolerances are set for PLA. Hope you're lucky with other resins!!
It needs no supports if you orient the pieces correctly.

I've made a few of them, no photos around.
