pillar book-end with hidden storage

This is a roman pillar inspired book-end that prints in 2 parts. Plate 1 is meant for situations where the books will be to the right of the book-end. Plate 2 is for book to the left of the book-end and plate 3 is the top part. everything prints without supports as its in 2 parts. Because the pillar is hollow you can use is as a hidden storage or fill it with sand and glue it shut to give it more weight. however adding weight is not necessary because the book-end has a plate which slides under the books to hold itself straight and support the books.

It should be printable on a A1 mini.
