Teeth are cut at an angle, allowing for smoother, quieter, and stronger operation.

OpenSCAD is a script‑based CAD system that excels at parametric modeling. Countless user‑contributed scripts are available for generating gears, many built on the BOSL2 library. gear+generator+stl
Instead, she opened a raw code editor.
Determine your required gear ratio (e.g., a 10-tooth pinion driving a 40-tooth gear creates a 4:1 reduction). Teeth are cut at an angle, allowing for
The plugin (available on Autodesk’s app store) enables you to generate spur gears quickly. A real‑world project documented on Hackster.io demonstrates its use: a 3D‑printed gearbox was built by generating multiple spur gears with this plugin, then organizing them into an enclosure. The plugin prompts the user for basic gear information, creates the sketch, and allows further refinement within Fusion.
If you printed your gear generator STL and it spins roughly, use this checklist: The plugin (available on Autodesk’s app store) enables
These tools allow you to customize parameters like tooth count and module, then export directly to STL format.
offers spur, helical, and herringbone gears with a free online configuration tool. Set custom module, tooth count, width, and shaft type, then download ready-to-print files—designed to print without supports.
We’ve all been there. Designing gears from scratch in CAD software is tedious and prone to error. One wrong measurement, and your 3D print comes out looking like a grater rather than a functional mechanism.
