Sometimes gears are hidden. They just do their thing behind the scenes and magic happens. That's the story of the Fiddle Fob. In this 1"X 1"x 1.5" pendant an interior set of 3-D printed beveled gears allow you to spin one of the outer wheels and have the other wheels spin magically. The LED tucked inside (powered by a CR2032 battery in a printed battery holder) glows and changes color adding to the mystery. What you get is a beautiful light up pendant that you can wear and play with anytime.
