N20 Motor Hubs and Mounts: 3D Models to Print

This collection gathers 3D models for N20 motor hubs and the parts that go with them: mounts, wheels, gears and adapters. You can use them to connect a small geared motor to a wheel, a pulley or a chassis in a 3D printing project. The models come from several platforms, so the files and descriptions vary. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

How this collection is put together

Polyzon assembles this collection from search results on the connected platforms. Repeats and models without a preview are removed, weak matches go to the end, and the rest keeps the search order. Models belong to their authors — check the terms on each model's page.

About the category

«N20 Motor Hubs and Mounts: 3D Models to Print»

The models fall into a few groups. Wheel hubs and rims attach to the motor shaft and carry O-rings or tires. Motor mounts and clamps hold the gearbox in a frame. There are also pulleys, gears and adapters for scale models or small robots.

When choosing a model, check the shaft diameter and shape, the number of mounting holes and the distance between them. Look at the photos of real prints and the notes the author gives about material and settings. Some hubs are designed for a press fit, others for a screw, so the assembly method matters.

To refine your search, try terms like gearmotor hub, N20 wheel adapter, motor clamp or pulley. Related topics include micro gearmotors, robot chassis and small RC wheels. You can also search by the part you need, such as a rim for O-ring tires or a mount for a specific gearbox shape.

FAQ

Frequently asked questions

What is an N20 motor hub used for?
It connects the output shaft of an N20 gearmotor to a wheel, pulley or other part. The hub transfers rotation from the motor to the part you attach.
How do I match a hub to my motor?
Check the shaft diameter and the shape of the shaft end, such as D-shaped or round. Also compare the mounting hole pattern on the motor with the hub or mount.
Do these models need supports?
It depends on the geometry. Many hubs and mounts print with no supports, but overhangs and small holes may need them. The author's page usually shows the orientation and support settings.
Can I use these parts for RC models?
Yes, many are made for small robots and RC builds. Look for models that match your wheel size and axle type.
