I made this model with Google Sketch Up and then exported it to Pepakura Designer and unfolded it. Then exported it to Pepakura Viewer and exported it as a PDF. Kind of complicated but all you have to do is print out this PDF using Cardstock 110 and cut out the pieces and glue together with low temp hot glue. Just fold down where the lines are dot dot dot.. And fold up the lines that are dash dot dash and so on. You can lay the pieces down and trace them off on other material as well.
