Here is a mount to hold a GoPro Camera, using the shorty tripod, to a Minelab Equinox 600/800 metal detector. I printed all the pieces from ABS but I'm sure PLA would have worked just fine and been more stable on my Ender 3.

This design allows the shorty tripod with GoPro camera to be easily dismounted in order to capture other shots, such as live digs or scenery. The camera can also remain on the handle of the metal detector and rotated to pick up other camera angles, such as selfies or live diggin!

A video can be found on YouTube of assembly and testing for reference.
