Edit 12/11/2023 : I've just updated the base and top layers to fit together better, as well as having larger outside walls and deeper sand tray

This is my version of a spirograph mixed with a Zen Garden in order to create patterns in the sand by simply changing the magnets and spinning the gear on the side.

Every part of this model does not require any supports.

I created this for a competition on Printables as I'm a student looking for way to practice.

I have printed all of the parts and they fit together and work nicely, but I do not have any sand or magnetic ball of any sort to test this myself. Unfortunately, by the time I had noticed the competition, it only had 3 days remaining, so here's what I've come up with in the past 2 days outside of work & studying.

I will create more gears at some point for more patterns

As the magnets are evenly spaced from the center, the pattern for opposite magnets from the center will be the same - this is on purpose as you can use 2x (6x3) magnets, and 2x magnetic balls to half the time taken to manually spin the gear on the side and achieve the same pattern.

The center platform was left empty by design to allow you to add your own zen accessories to be surrounded by the patterned sand as this area is out of reach of the magnets.

Please let me know of any issues or just even any makes to see how it turned out :)

p.s. here it is on printables if anyone wants to like it for the competition
