How to model Planetary Gears; Requirements, Gear Ratios, Helical/Herringbone (Gears pt 5/7)

I show how to model a ring gear, how to set up planets, carrier and sun, joints and motion links, and making helical/herringbone sets. I'm using Fusion360, though it should work fine in other CAD software, and I 3D print the set to show you that it works. Files: https://www.thingiverse.com/thing:465...
