Molded Pulp Slab Packaging Tray

Create a parametric 3D CAD model for a thermoformed molded pulp packaging insert tray. The primary function is to securely hold a standard PSA graded trading card slab, which has physical dimensions of 5.375 inches (136.5 mm) in height, 3.2 inches (81.3 mm) in width, and 0.25 inches (6.4 mm) in thickness. Apply the following precise geometric constraints and features: 1. CENTRAL CAVITY: Model a central rectangular pocket to fit the slab. Add a 1.5 mm tolerance gap on all sides of the pocket (final cavity floor dimensions: 139.5 mm x 84.3 mm x 7.5 mm deep) to allow smooth card insertion and removal. 2. FINGER NOTCHES: Integrate two semi-circular finger-access cutouts (25 mm diameter) on the left and right vertical edges of the central pocket, breaking through the cavity walls to allow a user to pinch and lift the card. 3. OUTER BOUNDARIES: The overall outer dimensions of the square tray must be 180 mm wide by 180 mm long, with a uniform flange wall thickness of 2.5 mm throughout the entire part. 4. MANUFACTURING RELEASE (DRAFT ANGLES): Every single vertical and inner wall must have a uniform 3-degree outward draft angle (taper) relative to the Z-axis pull direction to ensure clean release from a molded pulp tool. 5. STRUCTURAL FILLETS: Apply a 3 mm radius fillet to all interior base corners and a 1.5 mm radius to all top exterior edges to prevent paper pulp tearing during production. 6. FLANGE LEVEL: Ensure the top perimeter of the tray forms a flat, continuous 10 mm horizontal sealing flange. Export the final geometry as a clean, parametric solid model.
