The prompt
A parametric quadcopter drone chassis featuring a central 100mm diameter cylindrical fuselage body that serves as a protective electronics bay. Radiating symmetrically outward from this central hub are four identical hollow rectangular arms, each 150mm long, angled exactly 90 degrees apart. At the tip of each arm sits a vertical, cylindrical motor mount pod with a 22mm outer diameter and an inner hollow core of 16mm to accept brushless motors. The bottom of the central fuselage features a flat, integrated battery tray with dimensions of 80mm long, 40mm wide, and 15mm deep, complete with dual pass-through slots for structural strapping. On the top cap of the fuselage, a grid of four standardized 20mm by 20mm spaced mounting holes is integrated for securing a flight controller board. The entire chassis maintains a uniform 3mm wall thickness, optimized for rigid FDM 3D printing, with 5mm radius fillets smoothing the high-stress junctions where the four arms meet the central fuselage body.
