Free browser tool
Open STL, OBJ, GLB, glTF, and zipped OBJ files, then rotate and inspect the model directly in your browser.
Local files stay on your device
Drop in a supported file or load a public model URL. The interactive Three.js viewer loads only in your browser.
Preview STL, OBJ, GLB, glTF, and OBJ packages supplied as ZIP files.
Files chosen from your device are opened locally and are not uploaded to PrintVerse.
Orbit, zoom, and auto-rotate to check scale, orientation, and visible surface problems.
Drag a supported file into the viewer or select it with the file picker.
Rotate and zoom around the model to review the shape from every side.
Use the visual check before slicing, repairing, sharing, or generating another model.
A browser viewer is useful for checking whether a file opens, whether the model is oriented as expected, and whether its visible surfaces look complete. STL stores triangle geometry, while GLB and glTF can also include scene data and materials.
A visual preview cannot prove that an STL is watertight or printable. If you see gaps, missing faces, or strange surfaces, use the STL repair tool to inspect open and non-manifold edges before slicing.
Move from inspection to guided image-to-3D and parametric creation in the PrintVerse workspace.
