Weighted Gyro (Print-in-Place Fidget)

Overview
This looks like a standard print-in-place gyro, but it hides a unique mechanical twist. Each concentric ring is digitally modified to have 100% infill on exactly one half, creating a heavy, off-center weight distribution.

How it Works
Because of the asymmetric center of mass, gravity takes over whenever you hold, tilt, or turn the outer ring. Instead of just spinning randomly, the inner rings dynamically cascade, tumble, and self-align to face right-side up. It gives the fidget toy an incredibly satisfying, fluid motion that feels like a precision kinetic sculpture in your hand.

Print Settings & Tips
 

• File Type: Please use the provided .3MF project file! The magic of this model relies entirely on the internal weight split. The .3MF includes the exact modifier blocks needed to automatically slice half of each ring at 100% infill while keeping the rest light.
   
• Supports: None. This is a 100% print-in-place design.
   
• Material: Standard PLA works perfectly. Using a filament with a bit of a sheen or color-shift really highlights the tumbling motion of the rings.
