robot dog 3d model

A low-poly mechanical robot dog with flexible joint connections for 3D printing. Features clearly defined articulation points between body segments and limbs. Simplified geometric design with minimal overhangs. Joint gaps of minimum 0.5mm for proper movement after printing. Flat bottom surfaces for stable printing. No fine details smaller than 0.8mm to accommodate 0.4mm nozzle and 0.2mm layer height. Parts connected with ball-socket or pin-hinge mechanisms. Segmented limbs with visible mechanical components. Industrial design aesthetic with smooth surfaces. Robotics-inspired head with simplified features. All parts oriented for optimal 3D printing without supports.
