The prompt
A highly precise, engineering-grade 3D CAD model of an ergonomic elbow brace designed for post-traumatic rehabilitation. The model must feature a dual-axis mechanical hinge aligned with the human elbow joint to restrict and control the range of motion. Include an upper arm cuff and a forearm cuff, both anatomically contoured with a low-profile, skeletal frame design to maximize ventilation. Integrate slots on both cuffs for adjustable Velcro fastening straps. The outer shell must exhibit a lightweight, high-strength aesthetic suitable for 3D printing in biocompatible nylon or carbon fiber composite. The interior surface must be perfectly smooth to accommodate foam padding. Designed cleanly in watertight manifold geometry, optimized for additive manufacturing with zero non-manifold edges. Technical, clean, matte medical finish.
