Here is a great project of homemade 3d printable casing for underwater photography made by MoonLanding. Underwater photographs show it works well and it's fully functional.
It consist of handles and enclosure mechanism mounted on thick acrylic pipe. The project is in development and end goal is to create fully 3d printed waterproof enclosure with only lens window as non-printed part.
Here are all the details, STL files and example photographs:
