lego baseplate 3d model

Create a precise 3D CAD model of a square baseplate compatible with LEGO-style bricks. The baseplate dimensions should be 15.7 × 15.7 cm (48 × 48 studs). The top surface must contain a uniform grid of circular studs evenly spaced at 8.0 mm center-to-center, following standard LEGO proportions. Each stud should have an outer diameter of approximately 4.8 mm and a height of 1.8 mm. The underside should be flat and structurally reinforced for rigidity. On the left and right edges, include interlocking connector tabs that allow multiple baseplates to slide and lock together horizontally and vertically, as shown in the reference image. Plate thickness should be realistic for injection-molded ABS plastic. Edges should be clean with slight chamfers. Ensure accurate proportions, symmetry, and clean topology. Export the final model in STEP and STL formats, suitable for manufacturing and 3D printing.Create a precise 3D CAD model of a square baseplate compatible with LEGO-style bricks. The basepl
