futuristic energy cube 3d model

Create a stylized 3D electric generator obstacle for an endless runner game. The object should look dangerous and futuristic, with glowing electric coils, sparking energy arcs, and neon blue and yellow electricity effects. The generator should have a compact, modular shape suitable for placing on a running track. Include animated electric sparks and a subtle glow emission. Use clean geometry, game-ready topology, and optimized low-to-mid poly count. Centered origin, scaled for a third-person runner game, no background, single standalone object.
