Terminator T-800 Endoskull measurements

[captainwarnock]

Hi all. I'm 3D printing a Terminator Endoskull and would like to see how much I need to scale this model up. Could anyone give me just some rough measurements on length, width, and height of just the skull. Like I said, doesn't have to be anything too exact, not looking to print an exact replica here, just something in the ballpark for a fun little side project.

Thanks in advance!!!
