This is my design for the CMF Phone Contest. It is a case on the back of the phone with butterfly wings and when the wings are closed, they can act as a phone stand in landscape or portrait mode. When the gears are placed and the wings are attached, You can turn the knob to make the butterfly wings flap. To assemble: Snap wings into clips, put axel through hole in the plate, attach the gears to the pegs, screw in knob, attach string such as fishing string to one wing, make it go through the opening in the axel, and attach to other wing. When completed, you should be able to turn the knob which should turn the gears and turn the axel with will open and close the wings.
The author marked this model as their own original creation.
