Refrigerator Magnet Gear Spinners

thingiverse

My child adores things that spin and refrigerator magnets, so when I saw her play with gear magnet toys at the museum, I immediately knew we had to get some. It's a simple set of customizable gears where you can press in a 608 bearing and magnet. The magnet was chosen because it fits perfectly into the bearing, but I suggest using a small amount of glue to keep it secure since tolerances can cause some to be looser than others. The gears also come with four optional locating pins that allow you to stack them together to create a gear train! Keep in mind that doing this makes them painful to step on!

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