Hinged and folding phone stand for larger and all kinds of phones. I wanted a portable phone stand that could easily be folded and carried around in my bag or pocket. The hinge is made with a simple ball and divot. I have found that some plastics are tighter than others but works well.
*Update -- here is a newer stand I have just added. It is collapsable and supports phones and tablets -- http://www.thingiverse.com/thing:1551828
