The prompt
Generate a 3D printable parametric model of a stackable rectangular desktop letter tray. Outer Dimensions: Length 410mm, Width 300mm, Height 50mm. Shell Properties: Uniform wall thickness of 3mm. Solid flat base of 3mm thickness. Top is completely open. Front Opening: On one of the 410mm wide faces, lower the wall height to 5mm to create a front-loading document slot. Smooth the transitional edges with a 5mm fillet. Stacking Feature: Add a 2mm deep recessed lip along the bottom outer perimeter and a matching 2mm raised ridge along the top inner perimeter to allow secure vertical stacking. Format: Output as a solid B-Rep STEP or 3D print-ready STL file.
