3:1 gear stages that can be assembled to get a gear ratio to any power of 3.
I needed to reduce the speed of a motor by a large degree. My first tries used a a worm gear, but I didn't have my support settings dialed in well enough to print one yet. I went with this design so it would be easy to add or remove stages depending on the desired gear ratio.
For my current project, I am using 6 stages of gear reduction. 3^6=729 so I have a 729:1 reduction in speed. Included with this is a 1:729 increase in torque.
