M12 mount adapter for Raspberry Pi Camera 1.3V and 2.0V

I created the model to fit the Raspberry Pi camera with the original lens mount removed.

I provided three different kind of lengths 3mm 6mm 9mm for different lenses, where wide angle lenses usually are quite short and need to be very close to the sensor itself for which 3mm adapter is meant. 6mm adapter should suit most other lenses. 

I printed this model with 0.25mm nozzle and 0.07 layer height with supports, I recommend using support enforcer 20x20x4 box to prevent supports on the threads.

After printing I cleaned up stringing with a quick pass of a lighter. And attached to the camera with screws that came with the lens (1.7x6mm screw).
