Perpetual Motion da Vinci Style IV

myminifactory

Perpetual Motion da Vinci Style IV is the final Perpetual Motion machine in my series of Mr. Da Vinci's Overbalanced Wheel models, designed for a classroom environment to inspire discussion of his work. I was asked to create these models to bring his two-dimensional designs into three-dimensional stylized classroom models. As with my previous version, Perpetual Motion da Vinci Style III, perpetual motion begins when the model is tilted backward, causing a magnet to activate a reed switch that in turn activates a motor turning the overbalanced wheel via a rubber band transmission. 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, it's still just an illusion. As usual, I may have forgotten a file or two, so if you have any questions, please don't hesitate to ask as I 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.
