HDZero Runcam Nano HD 8-12mm Lens Adapter

This 28mm adapter can be used with a generic CCTV camera housing to mount a 12mm lens. I chose this route as the 12mm thread is too fine to print accurately.

Part list:

o S Mount M12 Board Lens Holder 20mm Screw Spacing Black for CCTV Camera
o CaddxFPV 1.6mm Lens

Print in a dark material at 100% infill.
I used ABS, but any opaque material should be fine.
