Dive Camera Port Buoyancy Ring

thingiverse

This is designed to help improve buoyancy of underwater dive cameras using a 120mm port systems such as Hugyfot or Nauticam. This is specifically designed for Hugyfot to fit a 45mm port extension but could easily be adapted to other sizes. I've not yet tested it on Nauticam ports but when I do I will post an update. To complete this you need 25mm wide 2mm thick neoprene stuck to the inside to help it fit around the port smoothly. The two halves are fixed together with M5 25mm cap head socket screws and nyloc nuts. Print 2 float parts and 4 pins. I stuck the pins 2 into each half so it would only fit together one way as the Hugyfot ports have a slight lip on one end and the float accommodates this.
