I received a set of Dora the Explorer reading books; such a thoughtful gift! I kept them in the car so my daughter could read to me while we were in the car, however the books flew all over the place every turn or stop. I designed this holder to fit this book set. I imagine that this could be scaled or resized to accommodate other book set dimensions or anything else for that matter. I added hex design pattern to help reduce the amount of filament used and print without support.
