If you use the link for "Box", and click on "Download" in the upper right corner, you will get the model. This model relies heavily on graphics, and is a series of boxes, but because of the detail, multiple printing of pages, and a careful study of pictures could yield an outstanding model.

Yes sometimes the links for PaperCraftSquare can get a little iffy from time to time. Thanks for reminding us about the mirror sites Z.
