Free cross-platform 3D file viewer for STL, GLB, OBJ, STEP, IGES and more. Replaces the discontinued Microsoft 3D Viewer on Windows.



StlFixTool converts and repairs 3D and CAD files in the browser — STEP to STL, STL to STEP, OBJ, GLB and 3MF in both directions, plus mesh repair for holes, non-manifold edges, duplicate faces and inconsistent normals.



Modelist is a desktop app for makers that runs on Mac, Windows and Linux. It scans the 3D printing files already on a computer and turns them into a searchable gallery with visual previews. Files are indexed where they are and are never moved, renamed or changed.
