Highly detailed 3D-printable dual storage tanks with integrated piping, bund, ladders, catwalk and service valves. This diorama prop is modeled for HO / 1:87 scale and is ideal for model railways, industrial layouts and scale scenery. Clean geometry for reliable printing; fine surface detail preserves rivets, seams and pipework. Recommended settings: 0.1–0.2 mm layer height, standard support for overhangs, and typical infill for display models. Files include ready-to-slice STL(s) optimized for hobby printers. Paint, weather and fit to your layout as needed.
