For a project I'll be releasing soon, I needed to generate a pulley for a GT2 belt. Since I wanted to avoid the effort of drawing the pulley myself, I searched for a generator and found one on GitHub. Unfortunately, the generated pulley wasn't quite right, so I forked the generator and optimized it to meet my requirements.

The Function

The tooth alignment has been optimized, and the user interface has been made more user-friendly. The generator can now generate DXF code and display it in a text output field. This allows you to paste the code into a text file and then save the file as a .DXF file. After that, it's easy to import it into any CAD program and thus get the gear into 3D.

The generator can also output a G-coder (machine code) for a laser plotter. Since I don't use this function myself and therefore can't guarantee its functionality, I'm considering removing it.

The Generator

ToDos

I'm planning to extend the script so that the .DXF file can be downloaded directly and doesn't have to be copied into a text file, which then needs to be saved as a .DXF file.

must be saved.
The generator should be switchable between GT2, GT3, and GT5.
 So far, the standard function has been sufficient for me, and therefore I haven't made any further developments.
