Modular Hot Wheels Magnetic Drift Pad

Design a modular Hot Wheels magnetic drift pad with an assembled size of 300 × 200 × 100 mm, specifically designed for printing on a Bambu Lab A1 with a 256 × 256 × 256 mm build volume. Split the 300 mm length into two separate printable enclosure halves, each approximately 150 × 200 × 100 mm. Add strong alignment/interlocking features and screw holes so the two halves can be assembled securely. Create a removable top surface split into two printable plates, with a smooth flat surface for Hot Wheels cars. Inside the enclosure, provide a central motor mounting area and clearance for electronics and wiring. The motor drives a horizontal circular disc underneath the top surface. Create a separate 150 mm diameter, 5 mm thick rotating disc with a central motor shaft/hub mounting hole and evenly spaced magnet pockets around the disc. The disc must fit completely inside the enclosure and rotate freely without touching the enclosure or top plate. Design all components with practical 3D-printing tolerances, rounded edges where appropriate, adequate wall thickness, and no unnecessary supports. IMPORTANT: Create the enclosure halves, top plates, and rotating disc as completely separate CAD bodies/components. Do NOT combine them into one mesh or one solid. Each component must be independently movable, removable, and exportable as a separate STEP/STL file. Keep every individual component within the Bambu Lab A1's 256 × 256 × 256 mm printable volume.
