Refrigerator Magnet Gear Spinners

My kid loves things that spin and refrigerator magnets. So when I saw her play with the gear magnet toys at the museum I knew we had to have some. It is simply a set of customizable gears that you can press a 608 bearing and magnet into. The magnet was selected because it is the perfect size to press into the bearing, though I do recommend using a dab of glue to keep it permanent because tolerances can make some looser than others. The gears also have 4 optional locating pins that allow you to stack them to make a gear train! (FYI Doing this makes them hurt to step on!)

My gears range from 15 to 25 teeth but the magnets are strong enough that you could do more. Video Link: https://youtu.be/Kw-B28VF0A4
