The prompt

Draft an aerodynamic center fuselage section for a fixed-wing UAV. It must be a hollow shell printed in PA-CF. The internal cavity must be exactly 450mm long, 160mm wide, and 100mm deep. Include a flush, removable top canopy for battery access, and a dual-door bottom hatch for payload deployment. Add internal 20mm cylindrical channels running laterally through the top to accept interlocking carbon fiber wing spars. Ensure the wall thickness is optimized for 3D printing durability.
