Ok, thanks for the information.
It was another helmet I took from a molding section and unfolded it in pepakura. The scale said 0.693..., but it turned out it was over 30cm.
I guess the tutorials were right saying it was scaled for a 7 foot supersoldier.

Yes it is, you didnt scale it right, me being 5'8'' I used 26.5 centimeters, as the height.
How does your helmet fit, because I am also 5'8". I scaled it down to 22cm, but I'm still debating whether or not that is a good size.
I have the measurements set for 22.0cm high, 19.2cm wide, and 28.6cm deep. I think that might do it.
