This 3D cage is a dirty training cage which could be found in a hardcore Martial Arts gym or an underground "Fight Club".

This 3D cage was made in Maya. There are 12 separate meshes with corresponding textures, all clearly labeled.

The texture maps include bump and specular maps, and are ready to use. They were designed for customization, so it will be easy to add details by simply adding logos in an imaging program like Photoshop.

If using the OBJs, keep in mind there are 12 separate OBJ meshes that make up the entire 3D cage.
