Planetary gearbox
An exposed three-planet gear assembly.
An open, three-planet gear assembly designed to make a complex mechanism easy to explore. The exposed carrier, contrasting gears, and central shaft reveal how the parts fit together. A study model for your desk, your next mechanism, or your curiosity.

A starting point for making. These are original concept models. Check dimensions, tolerances, mesh intersections, and material suitability before fabrication. Assembly exports contain multiple parts; separate and prepare them in your CAD or slicing tool. Gear teeth are illustrative; this is a static assembly study, not a validated working transmission.
