Accurately modeled 3D-printable chassis for carrying two 20' shipping containers end-to-end. This miniature set includes a detailed container chassis with realistic frame, wheel hubs, suspension blocks and twist-lock mounts, plus two detachable 20' container bodies. Parts are split for easy printing and assembly (chassis, axle assemblies, wheels, containers). Ideal for dioramas, model railways and tabletop wargaming—designed to be scaled for common hobby scales and to print cleanly on hobby FDM printers. Files included: chassis.stl, axle_set.stl, wheel_set.stl, container_left.stl, container_right.stl. Recommended supports: minimal for chassis underside and wheel wells. Post-print assembly requires simple glue or pins; wheel axles press-fit into hubs.
