Leapstart Book Holder

This is a simple holder for our kids' leapstart books. The tolerances are pretty tight so you might want to scale the model up by 3% or so. I found that not all of the books are the same thickness so 1-2 of them fit very snugly inside the holder. 

Features a hex pattern to help reduce the amount of filament used. Still, this uses about 290g of filament and took my printer about 8 hrs
