Involute gear template

A template for creating an involute gear. Go to the equation and by editing "Diameter", "number of teeths", "hole diameter" and "length" you can create practically any gear you want. Then save the modified gear in different place and use it! In order for gears to fit together their module should be equal. In my model the module is "D/N". You can add this expression to the equation to see the value of the module.
