This is a series of adapter mounts I made to connect C and CS camera lenses to my Samsung NX Mini. The 1 inch by 1/32 threads are a bit fiddly on my printer, and the first time a lens is installed, it has to finish the cutting the threads. If you print one of these, you'll need to install a bit of conductive material (I used aluminum tape) to short the three contacts on the right side of the camera. This lets the camera body know there's a lens attached.
