This is jaw-shaped clip for small camera which is used with Gorilla Tri-pod. My new Gorilla Tripod is bundled with only clip for Smartphone. So I planned to design this.

Need small torsion spring(1mm thickness) and steel wire(1.2mm)

I designed with Fusion360. To make nut structure to mate with bolt, I selected ACME Screw Threads (5/16, 3.094mm radius) at Fusion360.

Joint base might depend on model and maker.
