STL Gear Generator. Our free STL gear designer is designed with simplicity in mind, making it easy for anyone to create custom gears for 3D printing. Whether you need helical gears for high-speed applications, heavy-duty double helical gears, or spur gears for simple, low-load applications, our gear generator has you covered. Try it out.
Our 3D spur gear generator helps you make custom 3D gears and export the .STL file for use in 3D printers and importing into CAD/CAM packages. And .SVG and .DXF export remains available too! This generator also allows for keyways to help connect the gear to its shaft. While any size (up to the shaft diameter) works, we'd recommend using ...
How to Use a Spur Gear Generator. Input the following parameters in our free gear dxf generator: Tooth Count – is set with the parameter "n" for Gear 1 and Gear 2. Gear Type – External spur gears use a positive tooth count, while internal spur gears use a negative tooth count. For a rack and pinion, set n=0.

There are a lot of gear design options, each with their own ideal purposes. Knowing which one is best for you is important for making sure your mechanism works at peak performance. While it’s unlikely you’ll be 3D printing generators or high-end water pumps, we’re going to briefly go over what kinds of gears best fit which uses so you’ll have a bet...
Spider-Man Web Shooter
1. Download: Thingiverse 2. Designer: MediWolf123 3. Price: Free Maybe not the first thing that came to mind when thinking about 3D printed gears, but definitely the first one I wanted to talk about. This working Spider-Man web shooter uses small 3D printed gears originally designed for watch repair to shoot webs just like everyone’s favorite web-head!
Walking Cat
1. Download: Thingiverse 2. Designer: JohnThinger 3. Price: Free Gears are an important part of many moving mechanisms, and this walking cat, featured in our top picks for 3D printing projects for engineers, makes for a great project both in general and also for testing out your skills with 3D printing gears. As well as being a fun toy and a great way to get used to the more complex designs 3D printing is capable of, the walking cat also uses plenty of different gears at different sizes and a...
Planetary Gearbox
1. Download: Thingiverse 2. Designer: Gear_Down_For_What 3. Price: Free Another great learning resource, as well as a fun print, is this planetary gearbox. It works like a numbered padlock, but with the inner workings visible to you. This not only looks cool, but also makes for a good introduction to the basics of gear functionality as well as a learning tool for children or beginners in mechanical engineering.
In this electrical age of ours, it can be hard to think about what gears are actually used for these days. Generally speaking, when we think of gears we often think of old factories, steampunk settings, and ancient Indiana Jones-style trap mechanisms. But gears do still play an important part in a lot of machines and tools even now. Most mechanical...
Different 3D printing filaments are better suited to different projects. Gears are designed to be in near-constant motion, so the filament you use should be durable to ensure longevity and reliability. The nature of 3D printing means you’ll be using plastic material that will never really be as strong and tough as something factory-made and metal, ...
As you’ve probably already guessed, 3D printing gears requires more preparation and precision than the average print. To make sure you get working gears, you’re going to need to think and plan ahead, especially if you’re printing your gears from scratch. Here are some helpful steps and tips to make sure you get reliable results.
Test no.2 – Backlash. Next, for testing the backlash and strength of the gears, we will use the following setup. One gear will be fixed with 4 bolts, and the other will be able to rotate with two bearings attached to it. The gears have a module of 2.5 and they are all 3d printed with the same settings.
