Update - version 3 can be found here which has an adjustable holder(iphone 3 to 6 Plus will fit easily) and is much thicker: http://www.thingiverse.com/thing:571082 Working off my original design found here, http://www.thingiverse.com/thing:115086 I came up with this. This version allows cables of any size to be wrapped around the back of the holder. Also you can mount the holder in three different positions - left, right and top. Should work with most smartphones and cases. Enjoy! https://www.youtube.com/watch?v=pRnFxCs3LWwPrinted mine using: Supports 10% infill 2 walls .30 layer height
