The prompt
Design a highly detailed, injection-moldable protective case for the iPhone 16 Pro Max that looks like a realistic 1980s portable cassette Walkman. Include raised 3D buttons (Play, Stop, Pause, Rewind, Fast Forward, Record), a transparent cassette window, speaker grille, molded screws, textured ABS plastic, and authentic retro styling. The front cassette door should open by pressing an “OPEN” button, allowing the phone to slide inside through a hinged compartment with a secure magnetic or snap latch. Include precise cutouts for the camera, USB-C port, speakers, microphones, and buttons, plus a TPU inner liner for protection. Optimize for injection molding with realistic mechanical details and premium manufacturable construction.
