If you have pepakura designer you can mirror the model in the program, others-->mirror invertion in menu bar.
If you have pepakura viewer I don't remember if it is possible, but you can print two set and reverse one (if you want a model made of paper) or simply turn each piece and trace the outline on the contrary (if you are using foam/cardboard).
Hope it helps you
