About this 3D model

I read a lot of journals and needed a way to make "tabs" that stick up to remind me that I "might" someday go back and find an interesting article. Meet the Tabinator3000! Place it under a page in a journal and slide your pen in the groove, then bend up the paper to make a Tab. By the way "3000" referes to about the number of identical tags I made in designing this Tool. Works well on sides, edges and corners and I use it for catalogs as well as journals.
