Soinds like a fun project! Would a 3D-printed box be strong enough though? And how would you get the transperency? You might be better off using a CNC mill to cut it out of a plexiglass brick. And even then, how would you make the waterproof seal?

There are lots of new plastics available including some that are water-clear. We had a pump prototype made recently where the rotor and housing were 3d printed plastic. We were able to test the design pumping a slurry of mud and small gravel. It worked great. You can 3d print a model and cast silicone around it, then use the silicone to make multiple parts from different plastics. It is now possible to print in 3d using sintered metal fused with a laser.

I would probably print the housing with an open back and use a flat piece of lexan for the rear cover. I would attach the front lens with a flexible bellows so that it could collapse when the camera is powered down. The only buttons I really need to use are the power, shutter and zoom. This design would not be for real underwater use but should survive an occasional dunking.
