I built this model from a series of photogrammetric scans I made of a domestic cat (/Felis catus/) skull. One of the things I am particularly happy with is that the manubrium of the malleus, the strut of bone that the eardrum attaches to, is clearly discernable on both sides of the skull as a distinct structure. On the original specimen this projection of bone is approximately 5.0mm long by 0.75mm wide. Not bad for a scanning system that I managed to cobble together for about $300. Admittedly such a small delicate structure will be hard to 3D print. Maybe if it were blown up a few hundred percent, I might try that just to have a domestic cat skull the size of a tiger.
