Gear Generator 2 Beta: The Open-Source Sweet Spot for Custom Gears If you’ve ever tried to design a gear from scratch in CAD, you know the pain: involute curves, pressure angles, root fillets, and backlash calculations. It’s pure math, and it’s tedious. Enter Gear Generator 2 Beta —the web-based tool that has quietly become the Swiss Army knife for hobbyist engineers and laser-cutting enthusiasts. Currently in its second major beta iteration, this free, open-source tool is redefining how quickly you can go from "I need a gear" to "I’m cutting a gear." What is it? At its core, Gear Generator 2 Beta is a browser-based parametric gear designer. Unlike bloated professional software, it focuses on one thing: generating clean, accurate, manufacturing-ready gear profiles. You choose the type, punch in the numbers, and export a vector file (SVG, DXF, or STEP for 3D). But the "2 Beta" tag is important. The original Gear Generator was a workhorse—reliable but basic. Version 2 Beta adds a significant leap in functionality while maintaining the minimalist, no-account-required spirit of the original. Key Features of the Beta gear generator 2 beta
More Gear Types: The original handled standard spur gears. The beta introduces internal gears (ring gears), rack and pinion, and even herringbone gears (which are fantastic for 3D printing due to their axial load cancellation). Real-Time, Interactive UI: Sliders for tooth count, module (or diametral pitch), pressure angle (14.5°, 20°, 25°), and backlash update the gear preview instantly. No "generate" button. Just drag and see. Advanced Fine-Tuning: You can now manually adjust the tooth tip radius, root radius, and addendum modification (profile shift)—critical for avoiding undercutting on low-tooth-count gears. Assembly Mode (Beta’s Killer Feature): You can drop multiple gears onto the canvas, set their center distances, and the tool will automatically check for interference and calculate the correct backlash. This turns gear design into gear train simulation .
Who is this for?
3D Printing Makers: Export STL files directly. The beta does a much better job of generating non-manifold-free geometry, meaning fewer slicing errors. Laser Cutter Users: Clean SVG/DXF output for plywood, acrylic, or metal gears. The path ordering has improved significantly in the beta, reducing stray cut lines. Robotics Hobbyists: Need a custom pitch for a planetary gearbox? The beta handles module and pitch diameter with precision down to 0.01mm. The Gear Generator 2 Beta is a powerful
The "Beta" Caveats It’s not perfect. Being a beta, expect occasional browser lag when generating complex internal gear sets. The UI, while cleaner than v1, still has some unintuitive icons—particularly the "constrain to grid" toggle. Also, the STEP file export for CAD integration sometimes produces faceted geometry rather than true curves, though this is being actively patched. The Verdict Gear Generator 2 Beta is a remarkable piece of free engineering software. It lowers the barrier to entry for custom gearing from "advanced CAD user" to "anyone with a browser." The fact that it remains open-source and ad-free while adding genuine pro-level features (profile shift, assembly simulation) is almost shocking. If you need a gear in the next ten minutes, skip the CAD headaches. Open Gear Generator 2 Beta. It’s not quite a full replacement for professional gear design suites like KISSsoft or GWizard, but for 90% of makers and prototype designers, it’s the best tool available—and it’s only getting better. Final Rating: 4.5/5 (minus half a point for the occasional STEP export glitch, but full marks for ambition and accessibility).
You can find Gear Generator 2 Beta hosted on its official GitHub Pages site or via evgeniysharapov’s original repository. As a beta, remember to save your projects locally—browser storage can be ephemeral.
Gear Generator 2 Beta is an updated, web-based tool designed for creating and animating complex involute spur gear systems. While the original version focused on simpler layouts, the Beta introduces advanced features for multi-gear chains and planetary setups. Core Features & Functionality Planetary Gearset Support : One of the most significant additions is the ability to configure planetary setups, including options for Sun Gear, Planet Carrier, and Ring Gear as input, fixed, or output components. Complex Chains : It supports three or more gears in a single chain, including both internal (inside) and external gears. Real-Time Animation : Users can control rotation speed (RPM) and direction, with a "Freeze" or "Reset" function to test mechanical logic before exporting. Precise Control : The interface allows for fine-tuning of parameters like Diametral Pitch (P) , Module (M) , number of teeth, and Pressure Angle (PA) . User Experience and Pricing Business Model : Unlike the original's one-time fee, the Beta has transitioned to a time-based model, such as $2 for a full day of access, which users have noted is cost-effective for one-off projects. Ease of Use : Long-time users of Gear Generator appreciate the low learning curve and the ability to quickly download designs in DXF or SVG formats for CAD or 3D printing. Limitations : While powerful for standard involute gears, the tool does not currently support exotic types like worm gears or non-circular gears. Pros & Cons Supports advanced planetary gear configurations Time-based payment may not suit all users Exports to standard DXF/SVG formats Limited to involute spur gears; no worm gears Interactive animation for visual testing Beta status may lead to occasional UI bugs Affordable for short-term use No direct 3D object export (primarily 2D profiles) For those needing specialized parts, alternatives like STLGears offer free basic generation, while more complex workflows often involve importing these 2D profiles into tools like Fusion360 or SolidWorks for 3D modeling. Are you looking to use these designs for 3D printing or for laser cutting ? Gear Generator 2 beta Real-time Simulation : You can start, stop, freeze,
Title: Back on the Grid: Why Gear Generator 2 Beta is a Total Game-Changer for Mechanical Design Published: April 12, 2026 Category: Product Updates / Beta Access If you’ve ever spent an afternoon wrestling with involute curves, module systems, and pressure angles just to get two cogs to spin without locking up, you know the pain. The original Gear Generator was a lifesaver for hobbyists and engineers alike—but let’s be honest, it had its limits. Today, we are thrilled to announce that Gear Generator 2 is officially entering Public Beta , and it is not just an iteration. It’s a complete rebuild from the ground up. Here is what you need to know about the beta, the new features that will save you hours of CAD time, and how you can get early access. From Static SVGs to Full Simulation The original tool was great for outputting 2D DXF files for laser cutters. Gear Generator 2, however, lives entirely in your browser with real-time 3D physics .
The Old Way: Guess a ratio, export, cut, test, realize the backlash is wrong, cry, repeat. The Beta Way: Drag a gear into the workspace. Drag another. Watch the collision detection highlight exactly where teeth clash before you hit "Export."
