Prototype Gear Assembly CAD Models

I need a clean 3 D solid model of a simple gear-and-shaft assembly, complete with its enclosing housing, so I can move straight into prototyping. The geometry has to be built in either AutoCAD or PTC Creo—whichever you are faster with—because I will reuse the native files later in our workshop...
