This static 3D model represents a heavy duty equipment transport cart designed for secret research facilities. The model includes a reinforced cart base, solid wheels, and a boxed cargo platform without moving joints or handles. All geometry is merged and simplified for reliable 3D printing. The model contains no textures and relies entirely on geometry. There is no rigging or animation. Thin wheel spokes and fragile details are avoided. The proportions are generic and suitable for underground labs, industrial science environments, or eerie facility dioramas. The smooth surfaces allow easy sanding and painting. The model is untextured and fully ready for 3D print.
