Sun Earth Moon Orrery

thingiverse

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. https://youtu.be/7yHJrtdoCHU Printing and assembling the orrery should be very straight forward. Please refer to the included exploded drawings for the assembly.
