summary

An interactive Rhino plugin called Ondulé converts parts into parameterized helical springs using medial-axis sampling and spiral generation, exposes sliders and direct spring-parameter editing, and embeds five joint types (prismatic, revolute, knuckle, cylindrical, ball) to isolate compress/extend/twist/bend behaviors. Mechanical tensile and torsion tests on 17 printed springs (TPLA) closely match theory, enabling stiffness prediction. Examples include jack‑in‑the‑box, a spring‑powered rocket, sensorized storytelling props and an assistive cutter; limits include print anisotropy, minimum joint resolution, and need for support/dissolvable materials.
