3D Printed Perpetual Marble Machine

In the past few years, we have covered plenty of cool “perpetual motion” gadgets. Scientifically, we don’t know how to create perpetual motion machines without breaking the first or second law of thermodynamics. A lot of these toys use some sort of electromagnetic mechanism to create the illusion of it. This one is 3D printed. It simply launches the ball to the top platform, so the machine keeps going as long as you have power.

This perpetual motion toy is 3D printed with PLA. It has a simple wooden base. It uses a 12V power supply. Unlike other similar models, this one can handle multiple balls without any issues.
