Interactive 3D CAD Demo of a Planetary Gearbox

An interactive 3D CAD web piece. The model chose a planetary gearbox on its own, with 3 planet gears and a correctly meshing 5:1 gear ratio. It supports orbit-camera rotation, an exploded view, and speed adjustment. The prompt is a single sentence and specifies neither the object nor the tools. Suited to mechanical-structure explainers, engineering short-video footage, or WebGL capability showcases.
