Planetary gearset spinner

It is model or planetary gearset Speed ratio = 6 Hold one hander in left hand and rotate other handler with right hand - cented part will rotate fast I print it with: 3 loops Concentic bottom and top surfaces 20% 3d honeycomb (for better mass centering) No support No brims But probably it can be printed with default parameters You need few drops of cianacraillate glue to assemble it
