rugged handheld computer 3d model

Create a realistic high-detail 3D model of a rugged military-grade handheld radio/communication device based on the reference images, featuring a thick armored black rubberized frame with reinforced rounded corners, visible screws, and three long external antennas mounted on the top edge. The front should include a large tactical touchscreen display showing maps, signal telemetry, graphs, and system diagnostics, while the internal view should accurately represent the open-back electronics including a detailed PCB with chips, heatsinks, capacitors, connectors, a small cooling fan, ribbon cables, wiring, and a large rectangular battery pack at the bottom. The overall design should match the proportions of a rugged field device—smartphone-sized but thicker—using realistic materials such as matte rubber, brushed metal, and textured plastic, suitable for a high-poly, game-ready or cinematic-quality 3D model.
