usi3d

A new format. The same object.

Open an STL, OBJ or self-contained GLB. Check its size, rotate the real 3D model and download it in a format that fits your next step.

Formats

Download as STL, OBJ, GLB or 3MF. STL and OBJ contain geometry; colours, textures and animation may be lost. GLB keeps supported visual materials. 3MF keeps solid colours where possible.

GLB uses metres and Y-up automatically. STL and OBJ do not store reliable units: choose those used by your source file.
