ophthalmic diagnostic device 3d model

“Create a high-quality futuristic prototype concept image of a compact handheld ophthalmic diagnostic device for Schirmer tear test strip handling. The device must NOT look like a USB drive, but should be a small smooth medical-grade hygienic capsule-shaped box with ergonomic grip. Show an exploded technical view with the outer casing separated into parts, revealing the internal strip-loading mechanism. Inside the device, multiple sterile Schirmer strips are stacked in a sealed cassette chamber to avoid contamination from fingers, sweat, oil, or bacteria. Show a step-by-step strip dispensing system where only one strip comes forward at a time through a guided mechanical channel. The strip must fold automatically into a clean symmetrical V-shape at the tip using an internal folding mechanism, specifically designed for easy placement on the lower eyelid during tear film evaluation. Clearly illustrate the folding process, internal guide rails, spring mechanism, and strip path. The cente
