This is a Leica camera model that encloses a Raspberry Pi Zero W with its connected camera. I used the MotionEyeOS software with it and have it set on the window sill next to the front door.

You can print the lens in 2 pieces and camera body in one piece or in several pieces. I printed the body one piece at a time so I could paint them easier as individual parts and then glued them together afterwards. They also print faster as separate pieces since they require fewer supports.
