STL Viewer
Preview 3D-printable STL files in your browser. Rotate, zoom, measure dimensions, and inspect models before printing.
Drag & drop an STL file or click Open File
Controls: Left-click drag to rotate, scroll to zoom, right-click drag to pan.
Note: Dimensions shown in the selected unit (default mm, standard for 3D printing). STL files are unitless — values reflect the model's coordinate units.
