Summary

A latching holder for the insta360 x3 tripod (16mm diameter). Used to adapt to standard 2-pronged action camera mounts. For instance, the video below demos using the holder to allow you to mount/carry your camera and tripod using a backpack strap mount (which you can buy here: https://www.amazon.com/dp/B07HR77DZ7).

Use at your own risk. I've tested this and it holds on to the tripod fairly well, but your mileage may vary and you're responsible for any damage you may incur.
