Detailed post-apocalyptic concrete crater designed for HO (1:87) dioramas and tabletop wargames. Features broken slabs, exposed rebar, scattered rubble and layered concrete detail to create a convincing urban-ruin centerpiece. Model is pre-oriented for printing and sized for direct use in model-railroad layouts; it prints as a single-piece terrain element but can be rescaled as needed. Recommended printing notes: - Scales: optimized for HO / 1:87; easily rescalable for other common scales. - Materials: PLA, PETG or resin for finest detail. - Layer height: 0.08–0.20 mm for best surface detail. - Supports: light supports recommended under rebar overhangs and deep undercuts. - Post-processing: drybrushing and weathering bring out concrete and rusted rebar details. Files included: single STL pre-oriented for printing. Use a brim or raft for best bed adhesion on FDM printers.
