3D printed PLA experiment using magnets to mesh gears for mechanical transmission with little noise created by the gear mesh. Demo has little torque but interesting nonetheless.

True. I would think though that direct electric drive would be better for that though. You don't really need gearing if you can attach a motor that achieves the right target anyway, and those can often be quite small. Like if you were trying to drive a fan (the high speed low torque application that comes to mind), it's almost certainly easier to hook it up the the motor.

It kind of reminds me of this: https://www.youtube.com/watch?v=uD7Lzv5fWhs
