The prompt
Generate a complete, fully unified single-assembly 3D model of a 6-axis articulated industrial robotic arm featuring a cohesive, streamlined industrial aesthetic with smooth, curved outer casing shells seamlessly blending into circular joint housings, inspired by modern professional robotic design. The model must consist of a single continuous assembled tree where the heavy lower base housing (220 mm long by 180 mm wide with four 6.5 mm corner mounting holes, an internal 3 kg counterweight cavity, a front rocker switch cutout, a 5mm LED bezel, engraved "KG" lettering, and an engraved BOM layout) transitions smoothly into a rotating turret platform. From the turret, the main structural links—an upper arm link and a forearm link, each precisely 400 mm in center-to-center length to reach an 800 mm total span—extend outward as single-piece molded casings with internal $10\text{ mm} \times 8\text{ mm}$ wire routing channels and internal joint spaces sized for SG90 micro servos ($31.8\text{ mm} \times 12.0\text{ mm} \times 32.0\text{ mm}$). Each rotational joint (base, shoulder, elbow, wrist pitch, wrist roll) must feature a cylindrical housing integrated directly into the smooth contours of the arm links, housing modular 3D-printable planetary gearboxes with 15-tooth sun gears and 63-tooth ring gears for a 5.2:1 torque ratio. The arm terminates in a multi-axis wrist and an integrated parallel-jaw adaptive gripper with high-friction pads and sector gear mechanisms. Additionally, generate a matching handheld remote control unit featuring 6 linear potentiometer knob cutouts, an ergonomic grip, and internal controller space. Ensure all components are arranged together in a single coordinated assembly layout with a $0.2\text{ mm}$ radial clearance for precision 3D printing.
