This magnet toy is great for exploring geometric shapes and the awesome power of MAGNETS. It is inspired by natural geometry and buckyballs, which are way too much fun. Unless you eat them. DO NOT EAT THE MAGNETS.
First, print the part.
Then press a spherical 5mm rare earth magnet into each chamber. You should have to press pretty hard to get the magnet in, and once inside it should be able to freely rotate. This lets the polarities automagically align.
The more pieces you print the more shapes you can make. Enjoy!
