The prompt
Create a simple 3D CAD model matching the attached Fixed_Frame_Water_Balloon_Launcher_Blueprint.pdf. Include: - Wooden base: 800 × 600 × 18 mm. - Two fixed wooden posts: 600 mm tall, with a 400 mm clear gap. - Diagonal wooden braces behind both posts. - Elastic attachments 550 mm above the base, connected to a soft 200 × 160 mm fabric pouch. - Two outside wooden reference guides, 600 mm long, with 50 mm markings. Show both at 40° on plywood angle plates. The frame stays upright. Only the guides adjust. Elastic attaches to the posts—not the guides. The guides are visual rulers, NOT sliding tracks. Keep the center open. No trigger, motor, top crossbar, or people. Use basic shapes and colors. Show labeled 3D, side, and top views. Label “Preliminary concept—teacher review required.”
