This fully 3D printed assembly converts 400 rotations of motion into 1 singular rotation through an unconventional method. Using two harmonic drives offset by one tooth, creates this drastic gear ratio.

This project was entirely inspired and reversed engineered from a similar project found on the web. The mechanism uses two harmonic drives each with a gear ratio of 20:1 to create a 400:1 gear reduction. All components of this design including the flexible material were fabricated with additive manufacturing methods. The design of the assembly was carefully engineered to yield a simplistic and intact product.
