Resize Without Distortion: Smart Scaling for STL Models

SmartScaler doesn’t scale your STL model as a whole; it scales only where it’s needed. Corners, holes, threads and other functional features can keep their exact size, while only the chosen regions grow or shrink. Five tools cover the typical jobs: making parts longer, changing a diameter, repeating sections or enlarging a single detail. Type in target sizes directly or measure between two points on the model, and see the result instantly in 3D. The app runs entirely in your browser, with no installation and no file uploads. Try it.
