Key Cam 3D Stereo Mount

This is a derivate of the key cam helmet holder by jfpion (http://www.thingiverse.com/thing:39890) check there first for instructions !
I love the 40$ cheap and awesome Keycam 808 #16 so why not put two on your helmet and film in 3D stereo.
I used the Thing from jfpion and put two of them together.
I also changed it so it is printable without support. You have to glue the center piece upside down into the holder, it can not fall out by itself though.
I made the main plate smaller but you can use the original one too.
You only need 'center piece A', if you dont have a 40mm M5 you might use 'center piece B' with two shorter screws instead.
