Now check this out, this might be a simple Imperial Stormtrooper helmet papercraft but if you look closely at the model you can see that it has all the right folds and curves. This is what papercrafting is all about, not only are the polygons kept at a minimum, it's smoothen out to create a near perfect replica of what you're trying to transform into papercraft (saves you the time of scoring lines over and over). The pattern is in PDO, don't forget to download the latest version of Pepakura Designer to view this one. Kudos to the designer.
