Go to the search for Involute Gears
You can search for me within that list and find the metric parametric file I shared. Since the file uses a Design Table to compute the necessary geometry from Module, Pressure Angle, and Number of Teeth you can use it for a custom module as you want.
Hesham Salem, (and anyone else reading this post): BEWARE! The Toolbox gears are merely a representation of gears. They are NOT true involute profiles, not even close, actually.
Though I am a big advocate of Toolbox I wish they would do one of two things regarding their gears. Either make them with parametric true involute profiles (my preference), OR clearly alert the user that they are NOT true involute profiles with some type of warning message.
