Sun - Earth - Moon system

thingiverse

This is an educational sun-earth-moon system designed to explain earth movements, moon phases, eclipses, seasons and more. It's all manual with no automation, making it very easy to operate. I originally used a basic blue globe for the earth but later switched to a textured earth globe made by bld, thanks for that piece! https://www.thingiverse.com/thing:17336 The same earth file was resized to fit my system and with the hole placed on the pole. Of course, the system is not in real scale. I created one straight earth axis and a tilted one, allowing me to exchange it during explanations and show the difference. You can print both or just one of them. I also made files for half of each axis, to print twice and glue together, which worked better for me. The straight axis has a more fluid movement and is easiest to travel from one side to the other. The tilted axis is a better representation of the system but it's harder to get the correct moves. If you find a better way to do it, please make a remix.
