Simple 3D Gear design software recommendation

[Leadhead]

For clarity, I am aiming at a full 3D file to cut conventionally on a 3 axis CNC. With the axis vertical and if practical a radial toolpath.
I believe I am almost there with a bit of caddery-pokery. Makes one very respectful of Art Fernety and his Gearotic software.

Out of interest, what kind of size/tooth count are you looking at? Tool choice would be interesting as well - small enough to get into the bottom of the tooth but still giving a decent finish?

Currently adjusting tooth parameters to be able to rough with a 3mm and finish with a 2mm bullnose. That is, of course, the small end of the small pinion.
Not able to answer you until that is resolved. Will post a screenshot then.
