Skull and cervical spine model 3D print model
This is a 3D print ready model. No non-manifolds. The size of the model is X45mm Y63.4mm Z82.3mm but it can ofcoursebe scaled to any size to suit your printing purpose.
There is no sphenoid bone (the one on the base of the sull, behind the jaw) or smaller cavities in order to have a nicely printable model. The vertebrae have the holes for vertebral artery. The skull in piece assembly is slightly higher resolution and has added detail, like frontal bone foramen and nose foramen.
If the scaling is too small in your slicer when you open the file, just go to the scaling and change the 100% to 1000%, so it scales it up 10 fold. For some reason some slicers don't understand the scale correctly that has been created with blender.
There are 5 parts total: cervical spine, half skull, half head that is solid, half head that is hollowed, a single solid unit of head-skull-spine
The model can be printed in 3 ways:
1) As a unified whole model (single piece) that can be easily hollowed with a good slicer program, such as Chitubox
2) In parts with fitting slots, where the surface anatomy head model is solid, and can be hollowed with your slicer program
3) In parts with fitting slots, Where the surface anatomy model is already hollowed, with a hole on the bottom for resin to leak out
