GoPro Gyro

My son recently bought a GoPro Hero4 Session camera. I designed the "gyro" for my work and customized it by adding a fixture/handle, making it fit the standard GoPro Hero line of accessories. You can find a camera mount here: http://www.thingiverse.com/thing:53680 and add a handle such as: http://www.thingiverse.com/thing:278035 or http://www.thingiverse.com/thing:487964. You only need 4 M5 nuts for the middle ring. The six holes in the outer ring is only there to strengthen the geometry. You may wish to use M5 nuts in some of them if you are planning to use the gimball with a more expensive (or heavier) camera than the GoPro. Thankyou to the community for sharing your designs. Please share photos if you make your own. You only need the following 5 STL-files: Ring1_Core + Ring2_Flat + Ring2_HexSide + Ring3 + 4xDybler_8.6_14.2mm.
