Ferro Kinetic Torque Condenser

I designed a series of prototypes using non-circular gear wheels to explore the efficacy of the Ferrokinetic Torque Condenser - an automatic transmission that my grand-father invented, but was never able to build. The challenge was to design non-circular gear wheels and supporting components that could connect with Lego parts used in the rest of the product. This required tight tolerances in the design, accounting for shrinkage during the printing process.
