OhMyGear Free is a procedural generator built with Geometry Nodes for creating customizable gear models. It provides parametric control over a single gear, allowing users to adjust properties such as height, number of teeth, radius, depth, cut, roundness, and twist. It also includes an option for smooth shading. This free version focuses on single gear generation and does not include the animation synchronization, speed controls, or advanced hole customizations found in the full release.
