candy mold tray 3d model

Create a precise 3D-printable candy mold tray designed for the Bambu Lab A1 Mini (180×180×180 mm build volume). The model is a flat rectangular tray with overall dimensions of 160×160×12 mm to ensure safe clearance. The tray contains 24 identical candy cavities arranged in a 6×4 grid. Each cavity is a smooth spherical dome shape with a diameter of 18 mm and a depth of 9 mm, optimized for hard candy or gummies. All edges are filleted with a 1.5 mm radius for easy demolding and stress reduction. The base thickness is 3 mm, and cavity walls are 2.5 mm thick for durability. The underside is flat with no supports required. The design is minimalist, food-mold oriented, symmetrical, and optimized for single-material printing (PLA or PETG). Ensure watertight geometry, no overhangs above 45°, and clean manifold topology.
