3DR Solo Gimbal Holder for GP Hero 4 Black (no weights)

I made this gimbal holder specifically for the 3DR Solo and the __Hero 4 Black__. It is designed to snap into place and hold the Hero 4 Black securely. A generic version of this [found elsewhere](http://www.thingiverse.com/thing:1469963) on Thingiverse has a large opening for the counter-weights used on the Hero 4 Silver and Hero 3+ Black. It will not hold the Hero 4 Black securely. This one will.
It has been modeled so that the opening is centered over the GP display. It has also been created
