Sony Action Cam Adapter to GoPro Mount
This is designed for use with the waterproof case of the cam.
Combined this from two other things:

and
http://www.thingiverse.com/thing:829847
added the knob from http://www.thingiverse.com/thing:31958
and
you should also print this bolt or use a metal bolt in the right size and length :)
