"Perpetual Motion Davinci Style II" is an updated version of my original implementation of Mr. Davinci's "overbalanced wheel" design over five years ago.

In this updated version, "perpetual motion" begins when the model is tilted backwards causing a magnet to activate a reed switch which in turn activates a motor that turns the overbalanced wheel. And "perpetual motion" ends when either the battery expires, the rubber band breaks, the motor gives out, or by simply tilting the model forward and tapping on the back near the reed switch to disengage the magnet. In other words, like the original, it's just an illusion.

The motor I used in the final design was a 30 RPM gear motor, however, I've used 150 RPM motors with success, they just spun too fast for my taste.

As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.

Designed using Autodesk Fusion 360, sliced using Cura 4.0, and printed in PLA on an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
