DIY OpenSource gopro type bracket clipsable mount for bike lamps

[Reivax]

For a few months I wanted to buy myself a mountain bike helmet, and I just bought a Bell helmet, since several of my wheeler friends had one and I liked its lightness.

They come with a GoPro bracket on top, so I decided to design a mount to hold 2 bike lamps, one facing the front and the other the back, in order to be seen when riding at night.

It clips on the GoPro bracket, no screw needed, and leaves the microUsb charging port accessible:

Here are the lights: http://www.decathlon.fr/set-vioo-clip-300-noir-id_8346518.html

 Each offer several modes: still or blinking, and 2 colors : white and red.

And the file to 3D-print the clipsable mount available here: http://www.thingiverse.com/thing:1595829
