3D Models for Motors and Motor Mounts (STL)
This collection gathers 3D models built around motors: mounts and brackets, wheels and shaft adapters, engine models and small motorized mechanisms. It is useful when you already have a motor on the bench and need a part that fits it, or when you want to plan a build before starting 3D printing. Many entries are designed for common small gearmotors, so the shaft diameter and fixing holes decide whether a file is worth opening. 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 for Motors and Motor Mounts (STL)»
The most common group is mounting hardware: plates, clamps and brackets that hold a motor in place inside a frame or housing. Next come drive parts such as wheels, hubs and adapters that slide onto a shaft, often a small D-shaped one. A third group is representational: engine models, some of them motorized, where the motor drives a crank, fan or propeller rather than a vehicle.
When choosing a file, read the author's notes first. Check the stated motor size and shaft shape, the number of separate parts and how they join, and whether the model needs supports or a particular orientation on the bed. Material and settings matter too: parts that take torque benefit from a higher wall count and infill, while thin decorative shells can be printed lighter. Photos of real prints show how the assembly behaves better than a render does.
To widen the search, try the terms people use for the same idea: gearmotor, N20, D-shaft, hub, coupling, adapter, bracket, mount, or the name of the device the motor belongs to. Related topics include robotics chassis parts, RC and drone frames, camera gimbals and pan-tilt heads, and mechanical models with cranks or propellers. Combining a motor term with a function word, such as pump, fan or turntable, usually narrows results faster than a single broad word.
