We are currently preparing the shop for launch. Payments are expected to become available in mid-June 2026.
In the meantime, feel free to explore the available features, try the visualization in Preview Mode, and download the free samples.
Thank you for your patience. We look forward to welcoming you soon.

Welcome to SolidGearsPro, the professional-grade web engine designed to bridge the gap between complex gear design and rapid prototyping. Traditional CAD software often requires extensive experience and time to model accurate involute gear geometries from scratch. We are changing that.
Powered by WebAssembly (WASM) and advanced mathematical algorithms, our browser-based configurator delivers manufacturing-ready 3D data directly on your device. Whether you are a mechanical engineer refining a prototype, a product designer, or a maker looking for high-precision components, SolidGearsPro gives you the tools to generate, validate, and export industry-standard gears in seconds — no installation, no bloat, just pure performance.
Exact involute, trochoid and Tredgold-based algorithms for reliable results.
From basic inputs to advanced parameters every detail to your requirements.
Heavy computation happens locally in your browser. Your data stays yours.
Optimized for 3D printing (STL) and professional CAD/CNC workflows (STEP).
Choose the foundation of your project. We support the most common industrial standards, including
Each type is engineered with high-precision involute and trochoid geometry.
Tailor your gear to your exact needs. Our configurator allows for deep technical customization for both the Wheel and the Pinion:
Visualize your design before you commit. Using our three.js-powered preview, you can generate a real-time 3D model of your Wheel or Pinion.
The Validation Advantage: The preview acts as a live verification of your parameters. If the model renders perfectly in your browser, it is guaranteed to export correctly as a high-quality 3D file.
Depending on your workflow, select your preferred output:
Experience a seamless and secure checkout process. We partner with Lemon Squeezy to provide industry-leading payment security and instant transaction handling, supporting all major payment methods.
After your successful purchase, you will be redirected to your personal download area. You will also receive a time-limited download link via email, ensuring your custom-engineered files are available immediately for your project.
Stop spending hours manually modeling complex gear geometries. Our tool provides instant, manufacturing-ready CAD files for a flat fee per configuration. No hidden costs, no recurring subscriptions—just pay for the high-quality data you actually need.

We believe in the precision of our engineering. To ensure our files meet your specific requirements and work seamlessly with your software or 3D printer, we provide free sample configurations for download.
For cylindrical gears (Spur and Helical), we use exact involute and trochoid geometry algorithms. This ensures mathematically perfect tooth flanks and root fillets.
For Bevel Gears, our engine utilizes an algorithm based on the Tredgold Approximation. This method maps the bevel gear tooth onto a virtual cylindrical gear, providing high mechanical accuracy.
Yes. You can manually adjust the Normal Backlash parameter. We recommend 0.1 mm to 0.2 mm for most FDM printers.
Depending on your selection, we provide high-fidelity STEP AP214 (.step) files for professional CAD work (SolidWorks, Fusion 360, etc.) and STL (.stl) files optimized for 3D printing and rapid prototyping.
Absolutely. Our STEP files are exported using industry-standard protocols, ensuring seamless import into all major CAD platforms including Autodesk Fusion 360, Inventor, SolidWorks, Catia, and Rhino.
Yes. Every purchased gear configuration includes a perpetual commercial license. You are free to use the generated parts in your own machines, products, or prototypes, whether they are for personal or commercial use. However, reselling the raw digital CAD files is prohibited.
Yes! We believe in the quality of our engine. You can download a selection of pre-configured free samples in the "Free Samples" section to test the compatibility and print quality before making a purchase.
Immediately after the checkout via Lemon Squeezy, you will be redirected to the download page and also receive a secure download link. This link is valid for 7 days. If you need to re-download your files after this period, please contact our support.
Our tool uses WebAssembly (WASM) technology. This allows the heavy geometry calculations to happen directly on your hardware. This ensures maximum privacy (your parameters never leave your computer) and lightning-fast performance without server-side lag.
