Parametric Label Block - Custom Bookshelf Label

This parametric bookshelf label block is made to help organize your shelves with clean, readable category signs. It works well for genres like romantasy, thriller, fantasy, horror, mystery, or any custom label you want to display on a bookshelf.

The design has a classic nameplate look with raised text, layered borders, and corner pin details that give it a polished decorative finish. It is simple enough to fit into many shelf styles, while still standing out clearly once placed in front of books.

One of the best parts of this model is that it is fully customizable in the parametric file. You can change the text, adjust the overall size, choose different end shapes, and preview different color combinations before exporting your final version.
