3d printed gear spins fast (1:81 gear ratio)

3d printed gears spin so fast by drill. I reached +10k rpm at 1:81.5 gear ratio. But until to get this point the gears and chassis were explode many times. I used PLA+ for all the parts and lubed with lithium grease many times.

I think this experiment can give us an idea about turning the 1:googol gear reduction.

This is the Turning 30,517,578,125:1 Gear Reduction!
