WOF is on the 405th, and he currently made a template/blueprint of the pistol. So he may be working on armor in the future. But you will find more help at the 405th.
As far as pepakura, it already is a template, just in 3D. You can still use it the same way, by just printing it, cutting it out, and tracing it onto any medium that you are using and attach the pieces together.
