How to model Bevel Gears using Tredgold’s Approximation (Gears pt 6/7)

Here I show how you can model a set of bevel gears in Fusion360 for 3D printing. I’m using Tredgold’s approximation to obtain tooth profiles, which is one of a few techniques. Another well-known one is the gleason system. True spherical involutes are used very rarely.
