gyro fidget spinner - tiny minimal inline / expandable / modular / chainable

This is designed as a minimal fidget spinner but designed in a way that multiple fidgets can be strung together to make a larger fidget. Print 3 and have a sortof car which still spins well. More than 3 and you have more of a fidget snake which is still fun to fidget with but doesn't really spin anymore. A single unit works great for small hands and would also likely work good as a platform for a gyro.
