tea tray 3d model

Create a single rectangular tea tray as a clean industrial product model. This model must be suitable for precise CAD modification and 3D printing. Do not add any decorative patterns, textures, or unnecessary details. === Overall dimensions (must be exact, in millimeters) === Length: 550 mm Width: 220 mm Total height: 35 mm === Geometry requirements === - Overall shape: rectangular tray with chamfered corners - Tray consists of: 1) outer frame (tray wall) 2) inner recessed surface - Inner recessed area is centered perfectly - Recess depth: 3 mm - Tray rim width (distance from outer edge to recess edge): 12 mm on all sides === Structural requirements === - Uniform wall thickness: minimum 4 mm - Flat bottom surface - No internal cavities except the top recess - Sharp corners are not allowed - All edges must have small fillets or chamfers (radius approx. 2–3 mm) === Modeling constraints === - Geometry must be clean, simple, and symmetric - No organic deformation - No exaggerated curves - No surface noise
