This stylized single‑drum road compactor is exported as a single 1:87 (HO) master STL tailored for HO model railroad layouts and compact diorama scenes. Notable features include a broad cylindrical drum with preserved curvature, a compact faceted engine hood, and a simplified ROPS cab silhouette sized to pair with HO figures. The file is a single mesh and ships with a short text note that shows example uniform scaling conversions for other common scales; we do not supply multiple pre‑scaled STLs. The low‑poly geometry is intentionally simple to make printing, cleanup and finishing faster—ideal for batch prints and kitbashing. Note: filename and silhouette suggest a Caterpillar association; identity confidence is low and this is a stylized prop rather than an engineering‑accurate reproduction. If you need exact prototype dimensions or additional pre‑scaled STLs, contact Miniature Reality for a commissioned pass.
