More Easel Apps: Gear generator!

I just noticed that when you import the gear the scale is all off. Importing a gear with a 1/4" axel imports at .98ish inches.

I was also wondering if it possible to have the generator just accept an overall outer diameter that would just get filled out with teeth?

It would be nice if the app supported metric (modul) dimensions. Its a bit stupid having to convert everything to imperial.
