The prompt

Design a hexacopter drone frame for facade inspection and cleaning, called "Wash Drone." Main frame: Central hub, a flat hexagonal plate, 180mm across flats, 4mm thick, carbon-fiber composite. Six arms extend radially from the hub at 60-degree intervals, each arm 260mm long from hub center to motor mount, 20mm wide, 10mm thick, tapering slightly toward the motor end. Motor mounts: At the end of each of the 6 arms, a circular motor mount plate, 28mm diameter, with 4 mounting holes (M3, arranged in a 19mm bolt circle) for 6 brushless motors, 2212-size. Propellers: 6 propellers total, one per motor, 13-inch diameter, mounted directly above each motor. Central body/payload bay: Below the hub, a rectangular enclosure, 130mm x 110mm x 65mm, with a removable bottom hatch for battery access. Mount points inside for a Pixhawk 6C flight controller (36mm x 50mm board) and a Raspberry Pi 5 (85mm x 56mm board), stacked vertically with 15mm clearance between boards. Camera gimbal mount: Front-facing 2-axis gimbal cradle, 40mm diameter circular mount, positioned at the front-bottom of the central body, angled 15 degrees downward from horizontal. Cleaning module: Rear-mounted housing, 90mm x 40mm x 30mm, containing a fluid reservoir (cylindrical, 60mm diameter x 80mm height) and two spray nozzle outlets (6mm diameter) angled 30 degrees downward, spaced 50mm apart. A flexible tether line outlet at the base of the body, 8mm diameter port, for a hose/tether connection running down from the payload bay. Landing gear: Four fixed skid legs, each 10mm diameter carbon rod, bent at a 90-degree angle, providing 90mm ground clearance, mounted at alternating arm bases. Battery bay: Slide-in tray for a 6S LiPo battery, 145mm x 51mm x 45mm envelope, secured with a velcro strap channel. Overall motor-to-motor diagonal span: 620mm (hexacopter, opposing arms). Total design should be lightweight, optimized for a 4.5-5kg MTOW to account for 6-motor redundancy and cleaning payload, with mounting holes and clearances suitable for 3D printing in PETG or carbon-nylon composite. All dimensions in millimeters.
