3D printed Sun Earth Moon Orrery

I have always been fascinated by astronomy ever since I was a kid. The motions of celestial bodies orbiting around each other were often shown with orreries in ancient times. This is my first attempt at designing a basic orrery with the sun, earth and moon. Too keep things simple the earth completes a full orbit around the sun for every 360 turns of the crank and the moon takes 30 rotations of the crank to orbit around the earth. I will be refining my design in a future version which will hopefully show the orbits of more planets with greater accuracy.
