You need a custom gear. You don't have a math degree. Your free CAD software keeps crashing when you try to make a circular pattern.

Luckily, the era of manual math is over. A allows you to input three simple parameters (Module/Diametral Pitch, Number of Teeth, and Bore Size) and receive a production-ready file instantly.

Free Gear Tool > Manual CAD Note to the user: Since I cannot browse the live internet, please replace "link in bio" with the actual URL of your preferred tool (e.g., GearGenerator.com , Involute Gear Calculator , or a Fusion 360 plugin).

Why waste 2 hours in CAD when you can generate a perfect, parametric gear in 2 minutes? There is a tool online that does all the math for you.

Whether you are building a robot, a clock, or a fidget toy—save your sanity and use a generator.
