This is a very easy-to-make balancing toy using tinkercad and meshmixer.

The purpose of this post is not simply to publish my work itself, but to introduce the way how anyone can easily create something similar.

To create a balancing toy you need to know the centre of gravity of that object, and you can easily do that in the following ways:

• Create a 3D model using a CAD application.

• Open the created 3D model in Meshmixer.

• In Meshmixer, you can find out the centre of gravity of the 3D model from Analysis -> Stability.

• Repeat the adjustment so that the centre of gravity is at the bottom of the 3D model.
