Fourier Orrey (Square Wave)
See the updated version: Complex Square Wave.
Models a 3-component, real-valued square wave as a complex 1D Fourier transform. 1st model of the Fourier Orrery collection.
A simple demo to prove viability. As the first design, it's hugely unoptimized and has long been superseded by better versions. It's reasonably light and stable, but the lack of tolerances for FDM makes it require a bit more torque than ideal. Post-processing can't fix all the current problems. There are currently no plans to complete the hand crank or motorized stand.
