futuristic robotic arm 3d model

Create a 3D-printable modular desk organizer with three separate components in a futuristic sci-fi generative design style. Segment 1: A pen and pencil holder with clean vertical walls, measuring about 80 mm × 80 mm and 100 mm tall, with a stable flat bottom. Segment 2: A small accessory container for erasers or sharpeners, attachable to the main holder, with outer dimensions of about 40 mm × 80 mm and 30 mm height. Segment 3: A slim LED desk lamp module connected by a thin curved arm that attaches to the pen holder. The lamp has three adjustable articulated arms branching out like a sci-fi mechanical lamp, positioned to illuminate a work area from 46 cm to 120 cm wide. Use smooth sci-fi surfaces and hints of generative design openings, but keep all walls printable, solid, and manifold. Make the shapes clean, functional, and ready for fabrication.
