The prompt
Create a two-layer robot chassis for CNC cutting from 2 mm acrylic. Use 2 yellow TT motors with wheels. Make a lower motor plate and an upper electronics plate. Lower plate: 160 × 100 mm with two TT motor mounting areas. Upper plate: 130 × 90 mm with mounting holes for ESP32, L298N and MPU6050. Connect the plates with four M3 spacer holes. Keep the design symmetrical and flat with simple round holes. Make it suitable for CNC 3018 cutting.
