Twisted torus

thingiverse

A twisted torus is a mathematical structure formed by twisting and looping a circle around its central axis. This shape has no ends and is continuous, much like a doughnut or ring. The twist can be uniform, meaning the same amount of twist along the entire length, or it can vary, creating an irregular shape. In mathematics, a twisted torus is often used to model real-world structures such as bridges, tunnels, and other curved passages. Its unique properties make it a useful tool for solving complex problems in fields like physics and engineering.
