Scaling Classic Predator head to 1:1 for 3d printing

[aidyj84]

Hi all, 
Thanks for letting me join the forum.
Just wondering if someone might be able to help me getting dimensions for the original Classic Predator head.

 

I only have a terminator that i've 3d printed as a reference.

Is it possible someone might have a 1:1 predator classic bust that might be able to help me with dimensions if possible?

Thank you so much in advance,

Here are some reference pictures i've been comparing to (tried overlapping 1:1 print of terminator T800

Greetings,

 

One thing you may want to consider as well with dimensions is that the original jungle hunter was scaled for an actor over 7' tall. Are you attempting to build a 1/1 scale model or something a normal sized person will be wearing?
