Where is the third dimension?
I asked my ChatGPT friend what length a gizmo with this cross-section would have in order for its material's density be similar to known materials. The answer was the gizmo should be 72mm (2.84 inch) long, in order for its mass to be 1.44 ounces (close to osmium or iridium).

Does not look a "chip" to me, LoL
