About this 3D model
For my new, easier to print version check out this link: http://www.thingiverse.com/thing:65810 This is an iPhone 4/4s case with moving gears on the back. It clips onto my phone perfectly with no wiggle room, and is still pretty easy to take off. I altered the original rivets to make them easier to print, and scaled the main case a little bit for a better fit. Other than that, only part orientations have been changed.
