A simple 3D-printed magnet polarity discriminator designed to quickly identify the North and South poles of a magnet.  A small reference magnet is captured in a cavity of the printed body, allowing the unknown magnet’s polarity to be determined by attraction or repulsion.  No electronics or power required—just a simple, reliable application of magnetic attraction and repulsion.
