One axis gimbal for VIRB Elite

This is a one axis gimbal for Garmin's VIRB Elite I made for my DJI F450 frame. The servo is an HS-5485HB. The CAD file (.pk2) can be opened with PTC Creo Elements/Direct Modeling Express 6. You can use the original Garmin mounting screw, I was just lazy to draw its 3D model.

I used ideas from the following designs, I hope you guys don't mind. Thanks!
