Polymend Live 2026 A free repair tool for 3D models that slicers refuse. Drop a GLB or STL and it clears stray scraps, closes pinholes, and rights reversed faces, then hands back a print-ready STL and 3MF with a before-and-after view. Everything runs in the browser, so nothing is uploaded. Open Polymend
Browser-based repair tool that auto-fixes GLB/STL issues and returns print-ready STL/3MF with a before-and-after preview; runs entirely in the browser.
