Excellent script! Generates nice clean stl files almost instantly. Thanks so much!! :)

Unfortunately my script is unable to create internal gears. If I get time over the weekend I'll look at my textbooks and see if I can figure out the required changes.

what variables would I change in this code in order to draw an internal gear????

From the command line execute a command like this:
python InvoluteGear.py 12 20.0 6.0 gear.stl


The first parameter is the is the number of teeth, the second is the pitch diameter, the third is the thickness of the gear, and the forth is the name of the output file.

Additional options can be used to control the bore size (--BoreDiameter), the hub size (--HubDiameter, --HubWidth), the pressure angle (--PressureAngle, default 20.0 degrees), and how fine the involute surface is with (--StepCount, default 10 steps).

Nice job!

Trivia question of the day: why is an "involute" toothed gear better than other gear tooth shapes?

Answer: Involute gear teeth have rolling contact for less wear and smoother running compared to other gear tooth shapes.

Nice! We need more involute gearing in things here. Sometimes things need to be functional.
