Summary

I tough I'd find a simple tripod here, but actually they mostly all need screws, and assembly.
So I dedided to swap my deception for a challenge accepted.

You just download the only one file. You print it, than it only takes a rubber band and like 20 seconds for your cell phone to be held on a tripod!

This is more like a proof of concept. You can remix it to remove the need of rubber band, to make it angle adjustable, to be able to put the phone in vertical position, etc.
