lighthouse rotation mechanism 3d model

Low-poly stylized lighthouse rotation mechanism from the 1920s, for a monochrome indie horror game. Heavy metal industrial machine with large simple shapes only: square base, four angled legs, large central gear, central shaft, top support block, side hand crank. Old, worn, believable, practical, abandoned lighthouse equipment. Readable silhouette, minimal detail, no fantasy, no steampunk, no sci-fi, no excessive bolts, no decorative parts. Game-ready prop, simple topology, easy to use in Blender and Godot. Avoid tiny details, steampunk pipes, ornate decoration, complex chains, fantasy style, sci-fi elements, polished modern look, excessive greebles.
