As said before, scaling is making the 3D models the correct size so when you print them and build them, they will fit you properly. In the Pepakura Designer program go to 2D Menu-> Change Scale-> Scale Factor. A small window should appear, with boxes for height, width and depth, each filled with default numbers for theitem. Measure the length of the body part the armor goes to and plug that into the height category, in mm. For weapons, look up the appropriate length, and plug that into the length box, remember to use mm! Remember you only have to fill in one box, the others will update according to what you plugged into the box you filled in. Click okay and the pieces on the 2D window will change in size.You may have to take your mouse and drag some pieces around so they don't cut across pages.

Make sure to scale correctly, it is such a pain to spend o much time on something just to find out it doesn’t fit.
Once you have scaled your file, print it and begin the tedious process of cutting all of the pieces out. It is also helpful to score (lightly cut) the dashed lines before you cut the pieces out.
After you finish cutting, if you have not done so already you have to score the fold edges of the pieces, (The dotted lines). This can be done with pens, using separate colors for mountain and valley folds, or lightly cutting with a razor knife. Make sure to use a ruler to get a clean score!
Once your pieces are cut and scored you will have to fold them, mountain folds are usually gray and represented by a dotted line (………..) These you fold like this /\. Valley folds are the opposite, being folded like a “V” and are usually represented by a red dotted and dashed line (._._._._._._._.).
Now comes gluing. Take your glue and glue the pieces together according to the matching numbers, some files do not have numbers, for files like those using the Pepakura Viewer program to click pieces to see how they connect will be your lifesaver. Using Pepakura Viewer also helps even if files have the numbers, as there are usually many pieces and finding one number out of 500 can be a pain.
