This mount was created to use with a Phantom 2V+ and a GoPro 4 Black. Simply zip tie the legs of the phantom to the mount and mount the GoPro underneath. The legs are tall enough for the GoPro to fit when the gear is on the ground.
Printed with a Makerbot and oriented upside down on the build plate.
UPDATE: This mount has been tested with the Phantom 3 and will mount successfully.
