Scuba BCD Bladder Flange

Scuba BCD Bladder Flange modeled off of DGX Flanges. In the pictures the red is ABS printed from my design, the black one is a DGX commercial product. I made mine parts interchangeable with the industry standard. the last picture is assembled with an overpressure/dump valve. Due to the thread generator I used having a relatively small number of segments, the printed parts together have a slightly ratchety feel as you screw them together.
