This New 3D Printed Stepper Motor Uses LEDs to Show Exactly How It Works

You may recall a recent story we did about a man named Anthony Garofalo, who had 3D printed his own working stepper motor. Certainly not the first 3D printed motor we had seen, it was very unique in its own right, and Garofalo had made the design files available for anyone to print out themselves. In fact, he created an entire Instructables tutorial to teach others how to do so, under the Proto G user name.
