Stack-chan Stepper Motor Visualizer

I printed this model with Prusa MINI+ & 3DChameleon Mk4 Pro (black: eSUN PETG, white: Reprapper PETG). It is for use with two neodymium magnets: φ8×3mm. You can see stack-chan rotating in the roll direction. About stack-chan: https://github.com/stack-chan/stack-chan
