This skull was scanned using the Peel 3D scanner from a skull loaned from the Animal Sciences department at Olds College. After scanning the skull was cleaned up in the Peel 3D software, then I sliced the horns off using NetFabb.
While modified slightly during the cleanup, this skull is still anatomically correct. The join lines, nerve holes, and a large portion of the skull structure on the back of the head are completely intact.
Ultimaker PLA Main, PVA Supports
While it would be possible to do this with standard supports, I recommend PVA if available.
