OBJ STL 3D Model Viewer is an easy to use tool to view your 3D models stored in OBJ or STL format.

How to use it:

- load an .obj model by selecting the folder in your device storage that contains the .obj file and optionally the associated .mtl and textures next to it

- load a .stl model by selecting the .stl file in your device storage

- once loaded, you can rotate, translate and zoom into your 3D model to inspect it
