This is the same design as my large gopro rig although the only modifications are it is smaller in width and the handles are printed with the base to make the design simpler to assemble. I have also added a version that accepts an 8-32 nut and bolt as "safety line" holder if your inclined to strap your camera to the rig for safety.
