military shelter 3d model

A 2-inch square tile base representing a military base terrain, with a detailed Quonset hut structure centered on top. The base tile is flat and measures exactly 50.8mm x 50.8mm, with a height of 2.3mm excluding the hut. The Quonset hut is a semi-cylindrical arched building, 40mm long, 20mm wide, and 15mm tall, with corrugated metal texture, small doors and windows, and subtle military camouflage patterns. Add minor base details like gravel texture or small barricades around the hut for a military feel, but keep it simple. Optimized for FDM 3D printing: watertight manifold mesh, no overhangs exceeding 45 degrees, minimum wall thickness 2mm, solid structure with no floating elements, flat bottom for bed adhesion, and support-free design. High-resolution geometry, realistic proportions.
