Samsung Galaxy S4 Desk Stand (for use with external case)
I designed this specially for use with my Speck case still on my phone. I did not want to have to remove my case just to put it into another case. If you measure your phone with a case on it and it is 12mm thick, you should be able to use this design.
This stand has a cutout for your micro-USB charger to plug in and a nice wire guide for said charger to be routed directly out the back.
Note: The STL will import into MakerWare in a very strange orientation. Simply use the rotate tool to ROTATE +120 degrees in the X direction and then MOVE it -32mm in the Z direction. You can also ROTATE in the Z direction if you want to watch the front of the case as opposed to the back.
This design was inspired by ppollioni's Desk stand. I did not, however, use his files to create my own. It was made from scratch on SolidWorks.
