This low‑poly motor grader is supplied as a single locked 1:87 (HO) master STL sized for model railroad and diorama use. The sculpt emphasizes recognizability at small scales: a long chassis with a mid‑mounted moldboard (blade), a narrow steering front axle with solid wheels, a raised enclosed cab, and simplified rear housings suggesting tandem drives. Surfaces are intentionally faceted and robust to improve print success on hobby FDM and resin machines; the blade and wheel volumes are thickened to avoid fragile features at HO. One HO master STL is included — Miniature Reality does not supply multiple locked scales. For FDM printing, orient the model so the wheel line contacts the bed to minimize supports underneath the moldboard; blade‑up orientation reduces blade supports but requires careful cleanup beneath the moldboard. Supports are usually needed for the cab overhang and recessed window cutouts. Use the grader in maintenance‑of‑way scenes, compact construction vignettes, or as part of a vehicle display. The file originates from a legacy automation stub and is presented as a generic, unbranded motor grader; it is flagged for manual review. For higher fidelity (handrails, spokes) or scale conversions contact Miniature Reality for paid reworks.
