This online generator of epicycloids and trochoids uses the method of linked gears (2-5), known as the spirograph, to create spirals and rosettes used for artistic purposes, visualization, or to generate patterns for 3D printing and design, such as protective or decorative elements known as guilloche.

Set the parameters of the generating “Ferris” wheels, as well as the speed and precision of the generation. You can export the resulting shape to an SVG file or a DXF CAD file (requires JavaScript)

Samples: 2-simple, 2-detail, 3-cross, 3-simple, 3-spiky, 3-detail, 4-detail, 4-square
