Magnetic Gears

Here is a simple magnetic gear demonstration. With the help of some cheap magnets (picture) and skateboard bearings, you too can make magnetic gears!

I used:
-0.4mm nozzle
-0.2 layer height
-100% infill
-no supports
You don't have to use these settings, but keep in mind that lower infill settings will cause it to be more flexible. This shouldn't be a problem if you use magnets as weak as the ones I used. The shafts have a snug fit and might require minimal sanding to slide the bearings on easier.
