Found this real easy to use gear generator. U$ 23 to download. Can export to .dxf files and others but not .stl. It only generates an outline. Use extrusion in your CAD software to adjust the thickness of the gears. There is an online demo.

There's also an add-in for Fusion that will generate it for you. It might just require a small amount of digging about. I personally use a take home license of the software I use at work for the most part, but Fusion has some interesting capabilities.
