metal loft bed 3d model

Design a detailed loft bed metal frame (skeleton structure only) with a clear open space underneath for a study area. The model must focus entirely on structural engineering and assembly, including all nuts, bolts, and connections. Do not include mattress, desk, or any soft furnishings. Structure: Standard single bed size (approx. 190 cm × 90 cm platform) Four vertical metal support posts extending to the ground Rectangular upper bed frame with evenly spaced metal crossbars for load support Safety guard rails on three sides (rear + both sides) Integrated fixed ladder with evenly spaced steps and proper climbing angle Material & Build: Use square hollow steel sections (e.g., 40×40 mm or similar) Industrial-grade steel construction Matte black or raw metal finish Connections & Fasteners (IMPORTANT): Clearly show nuts, bolts, and washers at all major joints Use bolted connections instead of welded-only joints where possible Include: Corner brackets or gusset plates Bolt-through joints on frame co
