STEMFIE Spinning Top [washer]

This simple STEMFIE project consists of only three 3D-printed parts and represents a spinning top, one of the oldest known toys. A fully-threaded BU2.5 screw serves as the vertical axis, while a BU3.0 washer maintains rotational inertia. Both components are secured in place by a 5 mm STEMFIE threaded nut. Spinning the top on the screw&#39;s rounded head produces a random, wandering motion. To achieve a longer spin time, a sharpened piece of filament can be inserted into the screw&#39;s axial hole. For more dynamic motions, try spinning the top upside down. Typically, this STEMFIE set can be printed in less than an hour, using approximately 2 meters of filament.
