coffin 3d model

Create a highly detailed wooden coffin as a standalone 3D model. The coffin should be a traditional hexagonal shape with thick wooden planks, carved grain texture, metal hinges, and large iron nails. Add cracks, chips, and aged wear for a creepy undead theme, but keep all features smooth and thick enough for resin 3D printing. Include a slightly angled lid with deep groove lines but keep it closed and modeled as a single solid piece. No body, no skeleton, no ground, no environment—only the coffin itself as one watertight object.
