GearEngine

A Blender Add-on that takes the pain out of setting up complex clockwork animations.

GearEngine focuses on one thing, and one thing only: Making objects spin. It simplifies the process of setting up drivers and calculating gearing ratios, by providing a unified interface that makes it easy to setup complex gear systems with just a couple of clicks.

Features:

• Both driver-based and constraint-based drive systems
• Multiple rings of virtualized teeth on each object for multi-output systems
• Supports spur gears, worm gears, and six planetary gear configurations
• Comes with an info panel that provides practical information for common configurations

GearEngine is still in the early phases of development. The current release — v0.0.5 — is a 'preview release' that's mostly meant for people who want to try out add-on without having to mess around on Github. Get the add-on here if you want the convenience of a packaged release, get it over there if you want the latest and greatest experimental stuff.

As development continues, the price of the add-on will go up. It will always be available on Github, though, because I take this GPL stuff seriously.
