Keychain geared fidget bolt

thingiverse

This versatile fidget toy is ideal for those tedious lectures or meetings with your boss. The components are printed directly in place, eliminating the need for assembly. When you turn the gears, both will glide smoothly along the threaded rod, ensuring they stay securely attached and never slip off at the ends. All parts have a precise 0.5mm gap between them, allowing for seamless movement.
