Remember that night when you realized your book report was due the next day? You know, the book you forgot to read? And now you have to put something together to impress the teacher, hoping that by presentation you might make up for lack of substance? 

Well, now you can print off a report binder on your own instead of begging your parents at 9pm to drive you to the nearest Staples to find a 5-pack!

This prints without supports and is fairly sturdy. However, don't force too much paper in and don't try to open it too wide, or the sides will snap (this is the 4th iteration of the design after the previous ones broke too easily). If you'd like to print off a longer or shorter one, just rotate it to align with an axis and then scale it along that axis.

Best of luck with your book report!
