3D Models of Differential and Gear Mechanisms
This collection gathers STL files for differential mechanisms, from simple gear sets to compound planetary gearboxes. It helps you find parts for RC builds, educational models and mechanical projects. You can compare how different designs handle torque and assembly before you start 3D printing. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

Comment cette collection est composée
Polyzon compose cette collection à partir des résultats de recherche des plateformes connectées. Les doublons et les modèles sans aperçu sont retirés, les correspondances faibles sont placées à la fin, et le reste suit l’ordre de la recherche. Les modèles appartiennent à leurs auteurs : consultez les conditions sur la page de chaque modèle.

«3D Models of Differential and Gear Mechanisms»
The collection includes open differentials, limited-slip and torque-sensing units, planetary gearboxes, and compound gear trains. Some are designed as working mechanisms for RC cars, while others are static educational models. Differences lie in part count, gear ratios and whether the design uses printed bearings or standard hardware.
When choosing a model, check the listed size and scale, the number of parts, and whether the author expects supports. Look at the recommended material and slicer settings, and review photos of real prints to judge tolerances. Assembly instructions and clearances matter for moving parts, so verify that the design matches your printer's capabilities.
To narrow results, try synonyms such as gear differential, planetary reducer, or torque-sensing unit. Related topics include RC drivetrains, robotic joints, and mechanical teaching aids. Combining a mechanism type with a mounting standard or nozzle size can help you find a closer match.
