Tethered Underwater Camera

Thats a pretty cool frame? Got a 3d design file you can share? I assume that is for the 4" enclosure? I’m trying to get one in the 2" with an rpizero to do some local processing for a towed application. Trying to figure out my tray setup and also my tow tether which is right now going to be coax.

Thats a very nice frame. I’m trying to do one for the 2" enclosure but hoping to get lower CG and mount off the lower two front taps on the back of the flange. Also, I hope to do some local video processing with an rpizero2 and tethering it via coax.
