Three Spinning Reels_Independent Patterns_No Hardware Required—Mini Slot Machine

Thanks to Feihuolun's mini slot machine, I made significant optimizations and modifications to it:

1. No hardware or other accessories are required; just print directly;

2. The problem of the joystick breaking easily was solved by splitting the print and optimizing the force direction, so it won't break even if shaken hard;

3. The original version had one large roller, which was optimized to 3 independent small rollers, allowing for more pattern combinations when shaken.

Hope everyone has fun
