Free Blender 2.81 Drivers Example: Gear Press Mechanism (tutor4u)

Overview

This free Blender 2.81 file from tutor4u accompanies the second episode of the Blender Beyond Basics series, which introduces Drivers as a powerful animation tool. The scene is a gear-press mechanism (gear_press.blend) in which drivers read the location and rotation of one object and use those values to control the location, rotation and scale of others, so the whole machine moves from a single input; the renderer is not stated.

The .blend (about 2 MB) is a free direct download from the creator's website, linked in the video description. A clear, small example for anyone learning driver-based mechanical animation in Blender.
