Python script generates custom involute gear STL files for any project
Parametric design lets you dial in tooth count, size, and more
Perfect for building mechanical prototypes, toys, and moving parts
Ready-to-print output—just run the script and load your STL

This is a handy Python script that generates involute gear STL models you can 3D print on demand. Whether you're building a toy mechanism, prototyping a gadget, or just need custom gears for your latest workshop project, this parametric tool lets you specify exactly what you need—tooth count, pitch, diameter—and spits out a print-ready file.

Involute gears are the gold standard for smooth, efficient motion transfer, and this script takes the guesswork out of modeling them from scratch. No CAD wrestling required—just tweak a few parameters, run the script, and you've got a gear that fits your build.

Ideal for makers, hobbyists, and anyone who wants to add functional mechanical parts to their 3D printing toolkit. Print as many gears as your project demands, in whatever size or configuration you dream up.
