I engineered a sleek, protective book sleeve designed to safeguard novels and tablets during daily commutes. Developed in SolidWorks, the project balances structural rigidity with a slim profile, featuring secure magnetic closures, reinforced impact corners, and an ergonomic exterior texture. The CAD layout was optimized using DFM guidelines for soft-touch overmolding and flexible polymer extrusion. I delivered precise production files alongside high-fidelity product renders showcasing realistic textile and leather finishes.
