I've been using OpenJSCAD (demo at http://openjscad.org/) for small parts and really like it. With some work it could probably do what you describe but as far as I can tell no one is using it that way.

It would be cool if there was an ecosystem of OpenJSCAD parts that you could import as javascript modules.

Yeah, one should be able to import a part through a URL, and parametrize it ones own system.

I built the URL part out into a little side project. It uses OpenJSCAD but only the OpenSCAD interpreter so it can render the STL for you on the server.
