This is my skull.
It's a fairly complex model extracted from a CT scan using the Osirix Lite software. There is still a lot of noisy artifacts in the model from external elements picked up by the CT scanning process (air mask, tubes). I'll eventually do a cleanup of the model to eliminate those.
Nasal area of skull is splayed outwards in this model, due to impact from a car accident.
Works well with SLS printing; I've successfully printed it on FDM using Cura and an Ultimaker 2+.
