For iPhone 4/4s
This is a version of the iPhone Gear Case that I completely designed and drew myself. It is much easier to print than the first case, as well as being stronger and a better fit. The areas beneath the buttons and sliders has been removed to make them easier to use, and a cutout has been made around the headphone port so bigger jacks will fit without having to remove the case. The edges of the case are also tall enough to prevent the screen from touching when placed face down. I added a bevel to the ledges that hold the case onto the phone that makes the case very easy to print without support.
Here's a video of the gears in action

I got the Geneva Mechanism idea from jessed, and used msruggles' solidworks gear generator to create the gear profiles.
