This listing is for a detailed HO (1:87) master STL of a 1980s-style municipal fire ladder/utility truck. Modeled from a near-side profile photo, the file preserves the cab and front bumper geometry, exposed wheel hubs, two side compartment doors with recessed seams, a lower side skirt with a bolt/rivet row, and rooftop ladder/boom mounting hardware. The photograph used as reference had a large occlusion over the rear/top-right quadrant; the rear aerial components and tailboard are therefore intentionally simplified in the model and marked as unknown in annotations. The product ships as a single locked 1:87 master STL intended for hobby printing and layout placement. Printing tips: for FDM use 0.12–0.2 mm layers with supports for the cab roof overhangs and ladder rail; for resin printing use 0.05–0.06 mm layers and minimal contact points on small brackets. Thin features have been modestly thickened to survive handling at HO scale. No manufacturer logos or readable text are present. Ideal uses: HO model-railroad layouts, urban dioramas, and vehicle display collections from the 1980s era. If you need a different nominal scale, rescale from the 1:87 master in your slicer—the listing includes only the HO master STL.

Available railroad scales: Z (1:220), N (1:160), HO (1:87.1), S (1:64), O (1:48)
