About this 3D model

Inspired by "Gopro - Swivel mount" which designed by 3D_CC_design. I have re-designed it for my needs, such as breakaway design because my sport skills are not that good yet. With breakaway design, it might be safer. http://www.youtube.com/watch?v=9LizdBh_b-Q&feature=youtu.be http://www.youtube.com/watch?v=-0p2nJsMJNI&feature=youtu.be 2014/03/30 Updated stl files and instructions. 2014/05/11/ New video: http://youtu.be/FsndKbkFV7w 2014/05/17 New video to show brake away design worked: http://youtu.be/iaoP9MC4U7c
