I just hand modeled it (using Modo) based on orthographics I took of my head (screenshot 89). That's how I make most of my stuff.
It was actually had a caricature of myself lying around which was surprisingly close to my actual head shape (arnoldRender01), so it was relatively easy to modify it to fit my head.
I ended up bending the PLA slightly with hot water on the final print since the sides of the head were ever so slightly tight in certain areas.
