GoPro Hero 3 Case Backplate w/out Hinge stick
thingiverse
There is the opened and the closed Backplate for The GoPro Hero 3 Cases. I got two versions of it : - With hinge stick - Without hinge stick ( recommended ) I would not use the closed one for underwater filming. For sure you will need a sealing, but even then there is no guarantee for a total waterproof design. There are also a few holes on each side, for the microphones. I'm still at work, to find out the best scale. But by the Dimensions it fits well. You'll need a carpenter nail or metal stick for this ( hinge ). It should be at last 60 mm long and 2mm in diameter.
