A fun case with moving gears. Added a kickstand to hold the phone upright.
Print all of the gears and the top and bottom parts of the case. Also print two copies of the volume buttons. Print one each of the silence button, the power button, and the home button.
Then you can put the gears into place inside the case along with the power, silence, and volume buttons. Print out a copy of the kickstand. With the top case you can flip it upside down and put the home button in place. Then slip the phone into the bottom case and assemble.
Follow this link to watch the kickstand sliding in and out of the case while the gears spin away: http://www.youtube.com/watch?v=dTKF5F90rvg&feature=youtu.be
