14-Tooth Gear 3D Models and STL Files

This collection gathers 3D models of 14-tooth gears for 3D printing, from small pinions to internal and spur gear variants. You can compare tooth profiles, mounting options and intended mechanisms before downloading an STL. It helps narrow a search when a project needs a specific gear ratio or replacement part. Polyzon does not confirm whether models are free, their price, license, official status, affiliation, safety or fitness. Check the current terms at the source.

«14-Tooth Gear 3D Models and STL Files»

The collection covers several gear families. Pinions and spur gears appear for RC drivetrains and small motor setups. Internal and ring gears have teeth on the inside of a ring. Helical and bevel sets show angled teeth or intersecting axes, while construction-toy gear pairs use a shared tooth form.

When choosing a model, check the module or pitch, tooth count, bore diameter, hub shape and how the gear mounts to a shaft. The author's page may list the intended material, layer height, wall count and whether supports are needed. Photos of real prints can show how the teeth and bore turned out. If the gear must mesh with another part, match the tooth profile and center distance rather than scaling blindly.

To refine a search, try synonyms such as pinion, spur gear, ring gear, internal gear, bevel gear and helical gear. Add terms for the mechanism, like RC differential, extruder, stepper motor or toy axle. You can also search by tooth count and pitch together, or look for related topics such as gearboxes, pulleys and drive shafts.

FAQ

よくある質問

What does 14T mean on a gear model?
It refers to the tooth count in the model name. Tooth count affects the gear ratio and, together with module or pitch, the overall diameter.
How do I choose between spur, helical, bevel and internal gears?
Look at how the shafts meet: parallel shafts often use spur or helical gears, intersecting shafts use bevel gears, and internal gears have teeth inside a ring. Helical gears need a matching helix angle to mesh correctly.
What should I check before printing a 14-tooth gear?
Check the module or pitch, bore diameter, hub shape, tooth profile and the material and settings the author lists. Photos of real prints help you judge surface finish and how the part sits on a shaft.
Can I scale a gear model to match another gear?
Scaling changes tooth size and center distance, so the teeth may not mesh with an existing gear. It is better to match the module or pitch and tooth count to the mating part.
