Non-branded Articulated Military Heavy Truck — 1:87 HO master STL, ideal for dioramas, HO model-railroad layouts, and wargaming convoys. The model is exported as a single master STL where the tractor and trailer are modeled as distinct subassemblies and joined visually by a fifth-wheel kingpin interface. Visible features include a stout heavy-tractor cab with simplified mirror blocks and defined grille and windshield planes, exposed chassis rails and crossmembers beneath the cab, and a flat trailer deck with underside reinforcement ribs and dual-axle wheel housings. The geometry focuses on readability at HO scale and durability for hobby printing. You will receive one master STL file exported at 1:87 (HO). Recommended print approach: print tractor and trailer separately; lay the trailer deck flat on the bed to minimize support and get a clean surface finish. For FDM, use 0.12–0.20 mm layer height; for resin, 0.05–0.08 mm. Light supports are suggested under the coupling area and wheel arches. Conversion guidance is included for resizing to other scales (example multipliers provided). The model is intentionally generic and not licensed as any manufacturer's exact prototype. For alternate trailer decks, removable cargo, or multipart splits, contact the store for a custom version.
