A 30-tooth driver turns a 15-tooth pinion at an exact 2:1 ratio. The involute teeth are generated from a shared module and set one standard centre-distance apart, so they actually interlock and roll. The assembly tumbles slowly through every angle and cross-fades between the machined part and its blueprint on its own. Procedural in-browser — no model file — to show the quality bar before we drop in your real CAD casting.
WebGL isn't available in this browser — the production version would fall back to a static render here.
Like it? Send a GLB or STEP of the real gearbox housing and I'll swap this stand-in for your actual machine, lit like a studio render.
