Overview A low-poly heavy duty straight box (utility) truck prepared as an HO (1:87) master for hobbyists. The model reads as two clear volumes: a rectangular cargo box with large flat side panels and a plain roof, and a simplified block cab separated by a visible seam. Flat side panels are left smooth for decals or painting; corners are slightly chamfered to avoid razor-thin edges after slicing. The chassis and wheels are modeled as sturdy, forgiving geometry — wheels are solid discs to improve print success at small scales. What you receive One closed STL master mesh scaled to 1:87 (HO). This listing provides exactly one master STL. Use the included scale-conversion guidance to print at other scales; alternate-scale STLs are not included. Printing & finishing Orient the cargo-box base flat on the bed for the best finish on side panels and roof. Light supports are recommended under the chassis and inside wheel wells when those areas are exposed. Filament HO prints: 0.08–0.16 mm layers, 2–3 perimeters, 10–20% infill. Resin prints: hobby layer heights and low support density preserve planar surfaces. Post-process the cab/box seam with filler and sanding for a seamless result. Ideal uses: HO layouts, industrial dioramas, loading docks, kitbashing projects and fleet displays. Notes The mesh is intentionally generic and unbranded, originating from a legacy low-poly project. Use this model as a robust layout prop or a starting point for higher-detail modifications. Contact Miniature Reality support for scaling questions.
