GoPro Velbon Tripod mount

Works with Velbon tripod model CX 540, and most likely other tripods from CX series.

You'll need:
- one 10-32 acorn nut.
- one 10-32 thumbscrew
- 3/8 x .171 x 1/4 nylon spacers, depending on length of thumbscrew

The hex slot for the nut printed somewhat loosely on my printer but a little epoxy glue and it's a good fit.
