industrial robot arm 3d model

Professional 6-axis industrial robot arm, precise UR3e architecture for 3D printing. Structure: Modular assembly of straight hollow tubes and cylindrical drum-shaped joints. Joints Geometry: Axis 1, 2, and 3 feature large 55 5 5 mm diameter circular housings to fit Nema 17 ( 42 4 2 mm) motors with planetary gearboxes. Axis 4, 5, and 6 taper down to 35 3 5 mm diameter cylindrical joints for Nema 11 ( 28 2 8 mm) motors. Form: Single continuous arm, L-shaped shoulder offset, perfectly smooth straight upper arm and forearm segments. Engineering: Clean CAD-style surfaces, no decorative clutter, no external wires, no organic shapes. End effector is a flat 40 4 0 mm circular tool flange. High-poly manifold geometry, watertight mesh, 100% symmetrical. Optimized for STL export. Matte industrial steel and aluminum finish. Technical production-ready manipulator.
