Keep the same module, same materials, same greebles and window exactly as shown. Rotate/adjust the view slightly so BOTH the front and rear ends of the cylinder are clearly visible in one shot, isometric 3/4 view. The rear end must be an explicit mirror match of the front docking flange: same circular hatch door, same raised bolt-circle ring, same diameter and bolt count, same protruding coupling lip geometry as the front port. Both ends should look mechanically identical and clearly compatible for docking a connector tunnel. Clean isolated object on plain white studio background, no text, no labels, no collage.
