thingiverse

i made a c-mountable adapter base on this design https://www.thingiverse.com/thing:5495794 it has 46mm flange distance in respect to olympus OM lens to c-mount body if you want a macro just add 5mm extension c to cs mount spacer ring found here https://www.edmundoptics.com/f/c-s-and-t-mount-double-thread-rings/39560/ also a decent information can be found on site. i also made a mistake in c mount threads but you can force thread a 5mm metal adapter
