Motor Shaft Gears: 3D Printing STL Models

This collection gathers STL files for gears that mount on motor shafts, including spur gears, herringbone gears, compound gearboxes and adapters for small DC and stepper motors. It helps you find a starting point for a repair, a robotics build or a motorized model. Check the shaft diameter and mounting style before you print.

«Motor Shaft Gears: 3D Printing STL Models»

Gear models in this topic range from simple spur and herringbone gears to compound planetary sets, harmonic reducers and gearbox housings. Some are standalone gears shaped around a particular shaft profile, while others are complete assemblies with multiple stages. Small DC motor gears often use a press fit or a D-shaped shaft, whereas stepper motor versions may include a coupling or a mounting pattern.

When choosing a model, look at the shaft diameter and profile, the tooth count and module or pitch, and whether the gear is meant to mesh with another part. Check the number of parts, assembly steps, and whether the author lists supports, material and slicer settings. Photos of real prints can show how the teeth and bore turned out.

To refine a search, try terms such as spur gear, herringbone gear, pinion, gearbox, reducer, shaft adapter, D-shaft, or keyed shaft. Related topics include robotics, RC vehicles, stepper motor mounts and motorized scale models. Adding the shaft size or motor type to the query usually narrows the results.

FAQ

常见问题

How do I choose a gear for a motor shaft?
Measure the shaft diameter and profile first, then note the tooth count and module or pitch. Check whether the model is a single gear or part of a larger gearbox.
What should I check on the author's model page?
Look for the listed dimensions, number of parts, assembly notes, and any material or slicer settings. Photos of printed parts can help you judge the tooth shape and bore.
Do these gears need supports when printed?
It depends on the gear geometry and the orientation chosen in the slicer. The author's notes and example prints often show how a particular model was handled.
Can I use these models for robotics or RC projects?
Many gears and gearboxes in this topic are made for small DC motors, stepper motors, robotics and RC vehicles. Check the shaft interface and load before choosing a model.
