Piled Higher and Deeper

The title may or may not be stolen from a comic that I read regularly, although it is related to my latest model. The model is an arm reaching out from pages of a book as though someone (i.e. me) has been sucked into the textbook, and I figure the title "Ack!-ademia" works well. When originally getting a coming up with the book on its own, I managed to "re-design" David Brill's simple little book. The final design uses the same pattern with a bit of extra box pleating on the side. Here is the CP:


The layers get a bit thick in the arm, so I added the diamond in the middle to distribute them a bit better. Moving the diamond left makes a thicker arm but thinner cover (seeing as the extra flap can be hidden under the cover). Unfortunately, I didn't design the model quickly enough so for now I have to post a copy-paper rendition of the model.
