Help with gear

[Stanislavkt]

Hello

Brother gave me this part for 3d print.

First of all i want to ask, how would you create this part?

I´ve tried myself, but i got stuck at one point. Since i dont know any module and all i know is a number of teeth, im trying to do this with only with calipers and protractor. 

I hopefully did the larger gear right with the Add-in i downloaded.

What im trying to achieve is to have all six rectangles 6 milimeters away from each other, since thats what i measured.

Also, can i somehow snap it to the circle , so they dont overlap each other?

Would it be better if i imported a picture of the gear into fusion, or is it just a waste of time?

Hopefully you can understand what im trying to do.

Thanks for all the help

You can calculate the module by divide the diameter by the number of teeth + 2. 

Here's an example of a 24 tooth gear with 2 module. 52mm OD divided by 26 gives the 2 Module.

What is the outside diameter of the gear? How many teeth (I know I could count them from the image 🙂 )?  What is the diameter of the bore?
