Apparently ‘Disney Researcher’ is a job that really exists, and a group of them have just developed a way to calculate the exact distribution of mass within an object, in order to control its center of gravity. This allowed them to 3D print asymmetrical shaped tops, that spin despite their odd, off center shapes...
Checkout Disneys research on 3D printing. You can now convert any shape into a spinning toy. It does not have to be a symmetrical object. They have done this by using material of 2 different density. By changing where the denser material goes, they could get the object to rotate stably around an axis of their choice. Check the article to know more.

I designed and 3D printed a Brushless Direct Current (BLDC) motor, and used an Arduino to control the motor. All parts of the motor, excluding magnets...
When I was a kid, I always thought building a useful motor would be the most difficult thing. Looks like you can now 3D print a motor
