Bookshelf Label - v2

My daughter wanted some genre labels for her bookshelf, so this is what I came up with after a few iterations. This version has two pieces that are meant to be glued together via the alignment arrows. The name plate for the genre measures 75mm x 50mm, and the shelf attachment piece is designed to fit a 18mm high Ikea shelf (it fits on two different models of Ikea shelves in my house, but your mileage my vary) and is 20mm wide.
