A simple, thin protective case for the Kindle Fire (non HD). The kindle snaps in to the case to protect the back and sides. I printed this on the reprappro Mendel. No instructions really. Print and go. WARNING - the file Kindlecase_3.stl actually fits so well that when you take it off, it tries to seperate the kindle in to two parts.....kindlecase_4.stl has a cutout for the charging cable so it should be a bit more flexible.
