Core Structure: Tunnel and Height-Restriction Signage The main body is 3D-printed in a single piece using dark gray material, faithfully replicating the rough texture and weathered edges of a concrete tunnel to evoke the aged, eroded aesthetic of structures in a post-apocalyptic wasteland. At the top, a 3-meter height-restriction sign and a green “go” arrow are installed, complemented by blue-and-white directional posts at the entrance, accurately reproducing the detailed traffic signage found on real-world underpasses while enhancing the scene’s immersive storytelling appeal.
Road Surface and Safety Accessories The road surface features bidirectional guide arrows and yellow lane-dividing lines, paired with orange reflective pavement markers for rich, crisp detailing. At the entrance, red-and-white crash barrels are produced using segmented two-color printing, with clearly visible textures on the barrel surfaces and structural details at the tops, working in tandem with the blue-and-white guide posts to reinforce the sense of warning associated with “hazardous road sections.”
