This is a simple float design made for the GoPro. It was tested using the GoPro Hero 11 and its water proof case. It is a strong design with a hollow center. I was tired of the standard float you can find on Thingiverse so I created one that was slim and easy to grip.

For this build all you will need is an M5 Nut for the GoPro attachment point (Make sure to super glue the nut to accessory so it stays in place).
