Basically a standard-ish tricorder body, however....
...the display screen is flippable.
It's a 4-layer sandwich of images: 2 curved 'glass' screens, and 2 flippable display screen components between the 'glass'.
Screen 1 - Medical Tricorder on one side, and Science tricorder display on the other side.
Screen 2 - Geological Tricorder on one side, and Holly from Red Dwarf on the other (just as a joke). Inside in the storage area (hide the front of the storage area to access) is a blank display cube. The same as the main flippable display but blank so you can customize it with your own pics.
