This is an overly rugged case for the picam3 which is designed to be very strong, stable, and optionally waterproofable.

Note - It fits together tightly so once fully assembled it's difficult to pry open.

The main case is made of two sections, the camera fits onto the tags in the case then the lid pushes closed so the tab holds against the ribbon cable - ensure the cable is in correctly and the camera is working before closing the case.

The 'clamp body' clips to the back of the case, it will hold with friction but for a more stable fitting use glue.

The clamp body, arm and leg attach using M3 bolts (3.2 mm hole, the same size as the pi and picam). The Leg pushes into the base, glue is not required but can be used, the base can bolt down with four M3 bolts.

To waterproof first spray the outside of both parts of the case with something waterproof such as spray lacquer or paint. A piece of glass 30mm square should be cut to fit in the glass lid, fix this in place with silicone sealant to ensure no water can get in and fix this to the lid. Once closed add silicon along the join and around the ribbon cable.

Note - there is no airflow so be aware of the temperature of the camera, I use it for timelapse and have had no problem but with continual video in a hot environment an issue may develop, though in wet environments or submerged this shouldn't be an issue.

Warning - if waterproofing please be careful and pay very close attention to ensure it's properly protected before submerging or exposing to rain.
