Scuba diving camera tray for GoPro/SJCAM

thingiverse

I wasn't completely satisfied with existing designs so I created my own simple camera tray for an SJ4000 camera on a diving trip. The tray works just as well out of water, which is great too ;). \nThe SJ4000 uses mounts compatible with GoPros, and the size of its underwater case is roughly the same as the GoPro's, so a GoPro should work perfectly with this tray also. I designed the mount that holds the camera in place using a customizer and reinforced it to add extra safety and stability. \nThis design is extremely light and compact with great grip and super comfortable to hold (especially with rubber grips). The power/mode button and shutter button are easily accessible without having to release your grip on the handle. \nI'll be putting this camera tray to the test in late May at the Red Sea, Egypt. After that I might do some additional adjustments if needed. Will update here when I'm back from my trip. \nUpdate [20150608]: I got back from Egypt! The camera tray performed well and was used successfully underwater, plus it filmed a ride through the desert on quads. Since I don't have another device to compare video stabilization with, I can only say that the camera's footage still shook at times. However, this is understandable since the footage is being captured while moving around and possibly encountering surge or currents. \nIt was convenient having the option of holding it in either hand for added stability, or two hands for even more balance. The fact that the tray didn't feel heavy or bulky was another major plus. And most importantly, it wasn't obstructing my path. For buoyancy I simply inserted a small bolt with some washers and a nut into the hole at the base, giving enough extra weight (around 30gr) to achieve a slightly positive buoyancy in very salty water like the Red Sea's. \nFinally, I'm happy to say that all printed parts performed great underwater (max depth of 20m). Nothing broke, some water leaked through the infill as expected, but no damage occurred at all. If I were to do anything differently next time, it would be printing the base with a higher infill percentage to minimize its flexibility.
