I had a great phone stand that I had remixed to hold my iPhone a little better but it was kind of bulky to carry to and from work. So I went to the drawing board to try and make folding phone stand that would be a little more portable.

After some trial and error with the joints and space between them I've had two successful prints.

I had my printer set to .12 mm layer height to make sure the space between the joints for the hinges would work successfully. I used a raft for my print but you shouldn't have to if you don't want to.
