How could I make tooth gap and tooth amount depend on cog/gear size?

[Miserable_Haven]

This is what I get right now, unintentional degree and tooth amount for the big gear:

as you can see the tooth amount is the same which is supposed to depend on the gears size. The small gear is what I want the gaps to be like, and the big gear is not!!

What I’m asking:

How do I get the amount of teeth I need to create?
How do I get the degree I need to spread the teeth across the circles perimeter?

This is more of how it should be:

NOT MEASURED, just rotated the parts while running the game to give more understanding to my problem

yo wait did I actually ujst do it

I got ratio between gear base size Y(12) divided by normal gear base size Y (4) and for degree did 30/Ratio
