OpenSCAD module for simple gears with round teeth

Simple module that makes gears with circular-shaped teeth. The gears maintain their shape even for extremely low teeth numbers up to 2. Parameters:

  • teeth: number of teeth.
  • step: width of one teeth (diameter of the circle).

Two gears produced with the same step will transfer movement, so one typically fixes a step for all the gears and varies teeth for each gear, which decides the radius and transfer ratio. Example:
