This is a beefed up version of ppet36 iPhone Tripod. I needed it to survive in a suitcase during vacation so I just redesigned it to have thicker legs, etc.
I also uploaded separated pieces and rotated them to lay flat for ease of printing and strength of the final print.
I used a 8/32 x 2" Socket Head Cap Screw and Wing Nut to assemble it. You can use an elastic to secure the phone to the mount if needed.
There is two mounts.... one has a .45" opening the other a .50"
Overall it worked very well for taking pictures of the northern light while on vacation.
