Housing for REV 1.3 5MP Webcam Video Camera Module Board for Raspberry Pi

For my Raspberry Pi camera I created this housing. the housing has 8 screw holes; That's a lot but meant for closing the housing AND more mounting options.

The front has a ring for wide-angle lenses. Stick the provided metal washer inside the plastic ring on the housing. Then stick the lens with its magnet on the metal washer. The ring on the housing prevents the lens from sliding of.
