You mean a lens mount of the body? Could be easier to check if you find a broken Nikon in eBay and use it's mount. 3 D scanners are imo not precise enough. The mount has tolerances in fractions of mm, maybe ± 0.02 mm or less (I don't k now for sure). I don't know of a scanner resolving enough.
But maybe I misunderstood your question.
Or do you need the lens' mount of the lens? Then check out for an inversion or reverse ring like those

Any modern DSLR would do.
