Sun Earth Moon Orrery

I've been captivated by astronomy since childhood, mesmerized by celestial bodies dancing in the sky. Ancient astronomers used orreries to illustrate these intricate motions. As a first-time designer of an orrery, I'm attempting a basic model featuring the sun, earth, and moon. To keep it simple, I've set up the system so that the earth completes one full orbit around the sun with every 360 turns of the crank, while the moon orbits the earth in just 30 rotations. Future refinements will likely include more planets and greater accuracy in their orbits. You can see my initial attempt at this orrery in action here: https://youtu.be/7yHJrtdoCHU Assembling and printing the orrery should be a straightforward process. Check out the included exploded drawings for clear instructions on how to put it together.
