Detailed 3D-printable industrial steam boiler sized for HO (1:87) dioramas and layouts. This skid-mounted boiler model includes realistic piping, smokestack, manway, valves and flanges for an authentic factory or workshop vignette. High-detail geometry prints well on desktop resin and FDM printers; small supports recommended under the smokestack and piping. Ideal for model railroading, tabletop scenes, and scale displays. Files are provided ready for slicing; you may scale for other gauges if needed.
