Didatic model to show Planetary Gearset working. This is a STACKABLE model. You may print a single set or stack two or more sets to make a Compound Planetary Gearset. Some instructions (PDF included here) must be followed to assembly.
Each set, has a 1:4 reduction ratio. If you stack “n” sets, the final ratio is 1:4^n (4 raised to power of “n”). E.G., a stack of four sets, has the final ratio 1:256, i.e., you'll need to turn the input axle 256 times to turn output axle 1 turn…
Both axles may be attach to the crank. You may also print two cranks and attach each one to each axle.
A stand is provided, but you don't need to use it.
Best printed with PETG filament.
