How can i design this cog?

[Anonymous]

Hello,

I've just started learning Fusion 360 and want to print out this basic cog. The main thing i can't figure out is how to get the teeth to go all around the edges, I'm guessing i need to use the revolve tool but i just can't seem to get it right?

Also similar for all the arms in the center im guessing it's just a cut and revolve but i can't figure it out 😞 The center hole doesn't need to be anything more than just a hole.

Any help is appreciated! thanks

Sketch one tooth, extrude then use a solid pattern.

There is a gear script, look at the add-ins  (Shift+S) don't know if this is what you're looking for.
