sci-fi cube 3d model

A high-fidelity, hyper-realistic 3D sci-fi artifact cube. The cube is constructed from brushed dark carbon-steel and matte titanium panels. Each of the six faces features a unique, intricate mechanical design: one side has recessed geometric layers, another features a glowing crystalline icosahedron core behind transparent reinforced glass, and another displays complex micro-circuitry and server-grade cooling fins. The edges of the cube are framed by translucent neon light-strips pulsing with cyan and magenta energy. The design is clean, hard-surfaced, and industrial-futuristic, resembling a high-tech quantum processor or an advanced AI core. Sharp edges, realistic metallic textures, and cinematic ambient occlusion.
