This static 3D model represents a heavy power cable junction box designed for underground research facilities. The model features a thick reinforced enclosure with cable entry block shapes molded into solid geometry. No cables or wiring are included. The model contains no textures and relies entirely on geometry. There is no rigging or animation. Thin covers and screws are avoided to ensure reliable 3D printing. The proportions are generic and suitable for industrial science fiction environments, bunker interiors, or abandoned facility scenes. The smooth surfaces allow easy post processing. This model is untextured and fully ready for 3D print.
