3D Tutorial 11: Instantly Modeling Internal/External Gear Pairs in Blender

In this tutorial, you will learn how to instantly model the outlines of an internal/external gear pair in Blender using an online calculator we have developed, and then turn these outlines into full-bodied gears and test them for compatibility using Blender's Rigid Body Physics engine.

The tutorial will also demonstrate how to add a sun (center) gear to the system to produce a fully functional planetary mechanism, and how to test it with the rigid body physics engine too.

The end result of this tutorial, a .blend file containing a functioning planetary mechanism, can be downloaded via the link below.
