napkin holder 3d model

Create a precise 3D model of a napkin holder with a clean double-arch shape (like a wooden napkin holder), dimensions 180x60x80 mm. Include a centered straight slot (18 mm wide) along the length. Use uniform wall thickness 4 mm and a perfectly flat bottom for stability. IMPORTANT: keep the overall shape smooth, symmetric, and undeformed. Apply a strong crumpled paper texture ONLY as exterior surface detail. Texture depth 1–1.5 mm, with large soft folds and rounded creases, no sharp spikes, holes, or thin features. Texture must not affect edges or base. Interior surfaces must be completely smooth. Model must be solid, watertight, and printable without supports.
