Simple 3d Helmet

I’ve made a helmet with EVA foam, but the only problem is that it doesn’t look perfect ( as you can see on the pictures). Therefor, I would like to print this helmet with a 3D printer. But first, I need a 3d model of this helmet. I’m do not have the knowlegde to design this and already tried without success. My question is: Can someone help me to design this simple helmet? The measurements are in cm… see pictures `Link pictures Helmet
