handheld medical device 3d model

“Design a realistic 3D-printable handheld medical eye pressure monitoring device inspired by a digital infrared thermometer. The device should have a compact ergonomic grip, smooth curves, matte white medical-device appearance, and two equal attachable shell halves with screw-fit assembly. Include internal hollow space, wire-routing channels, PCB mounts, battery compartment, and electronics supports for ESP-C6, OLED display, and Wi-Fi circuitry. Replace the circular nozzle with a flat rectangular sensor head containing a square PPG sensor for direct skin contact below the eye. Add one USB-C charging port, one power switch slot, realistic internal spacing, and a professional biomedical diagnostic-device design optimized for practical prototyping and 3D printing.”
