Gear Sketch Diagram - Mechanical Design Reference #2009256 (License: Personal Use)

This hand-sketched gear features a concentric inner circle representing the hub, surrounded by a ring with twelve evenly spaced rectangular teeth. The lines are lightly drawn with visible pencil strokes, suggesting an early-stage design or conceptual draft rather than a finalized CAD model. Minor imperfections and construction marks indicate it was drawn freehand, likely for brainstorming or teaching purposes.

Used in mechanical engineering tutorials, DIY robotics guides, or introductory CAD courses to illustrate gear fundamentals; matches user intent for visual reference, design inspiration, or educational material download.
