Satisfying Ellips drawing tool

Ellipse Drawing Tool – Mechanical EllipsographThis is a purely mechanical ellipse drawing tool that allows you to draw clean, repeatable ellipses using simple guided motion.Inspired by classic drafting mechanisms, this design converts constrained linear movement into a smooth elliptical path, no electronics, no software, just geometry.Perfect for:✏️ Technical drawing & drafting📐 Geometry demonstrations🛠️ Makerspaces & education🎨 Creative sketching and pattern designHow it worksThe mechanism is based on a two-axis sliding system where a pen holder follows a mathematically defined ellipse. By changing the mounting positions, you can adjust the major and minor axes of the ellipse.FeaturesDraws smooth, accurate ellipsesFully mechanical (no calibration needed)Parametric proportions (ellipse size can be changed)Designed for standard pens or pencilsEducational and visually satisfying to useAssemblyAll parts press-fit or assemble with simple fasteners.
