gpt-inspired robot 3d model

Design a 3D-printable collectible desk mascot inspired by GPT as a calm, compact machine-creature. Use a blocky toy silhouette with a large square head, compact rectangular body, no arms, and a stable flat base. Height 60 mm, width ~42 mm, depth ~38 mm. Perfect symmetry, support-free, soft fillets, minimal detail. Face should have two small rounded-square eyes and a neutral expression. Add only one subtle AI cue: a small recessed chest core made of simple interlocking loops or six node-like shapes arranged cleanly. Avoid pasted-on logo detail, thin necks, busy patterns, generic humanoid limbs, or abstract sculpture vibes. It should feel collectible, intelligent, and quietly GPT-like.
