Responsive Yo-Yo (Ball bearing axle and spacers)

thingiverse

Tinkering with a Yo-Yo design that innovatively falls asleep at night, its string unwinding into a tranquil slumber. To activate it, all you need to do is gently tug on the thread, setting it back into motion. The goal is to replace the traditional string with a durable bolt that can be customized by the user themselves, adding an extra layer of functionality and creativity to this classic toy. To bring this vision to life, essential components like precision ball bearings and thoughtfully selected spacers must be carefully sourced to ensure seamless performance.
