Al you need is a 1/4 inch bolt. The socket on the “360” is a standard 1/4" tripod socket
So you drill a 1/4" hole in whatever you want to mount the camera to and attach a bold with washers and a nut.
You can also buy a standard “ball head” at a camera shop and use that in place of the 1/4" bolt. These are all standard parts available in any camera store.
I made a helmet mount by using a 1/4" bolt threaded upward from inside the helmet.
One tip: Use flat black spray pain on anything that is under the camera, it shows in the image. Black hides it.
