Reuleaux Prisms

thingiverse

The Reuleaux triangle is an iconic constant width curve born from an equilateral triangle's majesty. Each point on its side boasts equal distance from the opposite vertex, demonstrating sheer geometric brilliance. In layman's terms, this ingenious shape is part of the Reuleaux family, which also includes the circle - the original and most recognized shape boasting constant width. Once printed, these prisms can be placed between two planes where they'll behave like conventional cylinders, enabling you to effortlessly roll them back and forth. This innovative concept was cleverly utilized in an unconventional alternative to the standard four-stroke engine known as the Wankel engine. Post-printing these triangles can be placed between two planes where they will function like regular cylinders, allowing for a smooth rolling motion from side to side. However, some sanding is required to smooth out the edges, resulting in a natural and effortless rolling experience.
