I have it a little big because I'm going to be making it with stilts for my suit.
You will need to downscale it, to do that measure the width of your chest from armpit to armpit then convert the inches over to millimeters enter the number in the width in pepakura, then rearrange the pieces.
So far I've gotten the Chest and Back file done. This thread will be for the Pepakura Files for the MMPR Megazord for people intrested, thanks to a friend of mine Natsume Ryu from the Transcostumers (Transformers Costuming Forums) made the 3D Model for me for all the parts of the suit, and I have been unfolding the files.
