I made this object with the idea of recording videos with the same point of view that you have when you surf.

I imagine that you can also use this mount in many other occasions and sports (like kitesurf and windsurf for example)

Here it is a video that I made in a first test:

I printed this object with a 100% of infill to ensure it's resistance.

I bought the scuba diving silicon mouth piece in Decathlon for 5,95 € (http://www.decathlon.es/boquilla-silicona-brida-rapida-id_5744022.html) but I'm sure you can find it even cheaper in eBay.

I recommend tying a shoestring from the base of the mount to the neck (as a necklace). Just in case you open the mouth and lose your Gopro.
