Mechanical Spinning Top

thingiverse

This fully 3D-printed mechanical spinning top is more than just a fun toy - it's also an educational tool in multiple ways. As any spinning top would, it showcases the fascinating physics phenomenon known as the gyroscopic effect, which prevents the toy from falling over while spinning. Inside, there's a clever little mechanism that converts the back-and-forth motion of the spiral rod into one-way rotational motion for the spinning top's body. This is called the overrunning clutch, and we've successfully made it fully 3D-printed, including the torsion springs. This substantial toy measures 20cm at its widest point, making it a significant project. However, the parts are designed with ease of printing in mind, requiring almost no support - except for one part.
