fixed-wing drone 3d model

Generate a complete 3D CAD model of a fixed-wing UAV optimised for 3D printing in ABS plastic. The design is a conventional tractor-propeller configuration with a high-wing or mid-wing layout, cruciform tail (separate horizontal and vertical stabilisers), and a monocoque fuselage. All geometry must be parametric, hollow-shelled for printing, and structurally self-consistent.
