This is a mount which allows the Jakks Pacific Action Cam to be mounted onto the strap of a ski goggle . It could easily be adapted to strap onto most anything.
Print it out. You'll want a reasonable amount of infill so it comes out strong. Depending on your printer's ability to do overhangs, you may need to clean up the tabs a little. Feed the goggle strap though the slots in the mount. Attach the camera as you would on the rest of their mounts.
