This part protects the camera lens on a camera trap enclosure. The hood has an inner diameter of 83mm to accept an 82mm UV filter. I mounted the flange to the camera trap enclosure with silicon seal and (4) 3mm screws. The (4) screw holes are on a 112mm circle. 

I used a Lock-n-Lock Airtight Rectangular Tall Food Storage Container 152.16-oz / 18.8 Cup. I painted the container tan color.  My camera is Canon T2i with 18-55 mm kit lens. I made a 3d printed base to hold the camera at the correct height. The Lock-n-Lock container is not vandal or animal proof, use at your own risk. The camera enclosure has been out in the rain and my camera did not get wet.
