The prompt
"Create a clean, manifold, water-tight, production-ready industrial 3D CAD model of a structural robotic arm link with integrated servo housing for 3D printing. The overall bounding box dimensions must be exactly 180mm length, 30mm width, and 24mm height. Inside the main body, incorporate a hollowed-out rectangular pass-through pocket measuring exactly 41.2mm in length and 20.2mm in width to house a standard MG996R servo motor. Flanking this rectangular pocket, place two solid horizontal mounting flanges. Each flange must contain two precise mounting pilot holes spaced exactly 49.0mm apart longitudinally and 10.0mm apart laterally, with each hole having a diameter of 2.8mm. The structural beam section of the link must feature a lightweight open frame utilizing an internal repeating 45-degree triangular truss web pattern with a uniform wall thickness of 3mm. One end of the link terminates in a dual-shear U-shaped clevis fork joint with an inner gap width of 16.0mm. The opposite end terminates in a solid structural circular mounting boss featuring a 3.2mm pivot bolt hole. Ensure all exterior edges have a clean 1mm fillet radius. No floating geometry, no internal intersecting faces, completely flat bottom face optimized to lay flat on a 3D printer build plate."
