blue square tray 3d model

Generate a 3D model of a single memory-game tile designed for 3D printing. The tile must be a perfectly flat square with rounded corners, external size 40 mm by 40 mm and total thickness 3 mm. On the top surface, create a recessed cavity: an inner square centered on the tile, 1 mm deep, leaving a 3 mm border on all sides. Around this cavity, add a raised frame (a border) with 1.5 mm height above the top surface, forming a clean container to hold a printed photo and a layer of UV resin. All surfaces must be smooth and suitable for FDM 3D printing. The bottom surface must be completely flat. No text, no symbols, no images — only the blank tile design. The model should be watertight, optimized for printing on a 0.4 mm nozzle, with no extremely thin walls
