Nested Bookend / Bookend and Paperclip

While orgnizing books on the desktop, we used to arrange them from big to small, so it's a good idea to make two bookends a corresponding size with each end of the book. There are two purposes: The bookend corresponding to big book should be larger to make the books standing more steady; The opposite bookend should be smaller to save material. The small bookend is cut from the big one, and the smallest material cut from the small bookend shall be used as a paperclip exactly. If not in use, the paperclip can nip on the bookend. It is a nested design to make the best use of a piece of iron material and process easily by blanking and bending.
