Print in Place Planetary Gear Spinner

Print-in-place planetary gear spinner. Spins freely straight off the plate.

I set up two print profiles for this model:
Heavy outer ring - prints using 43g of filament to make the outer ring heavier. This gives it a bit more inertia, but feels heavier in the hand.

Light outer ring - prints using 29g of filament. Feels lightweight in the hand and prints faster, but doesn't have as much inertia.

Both spin great - I'd say pick the print profile based on how you want it to feel in the hand.
