This model is not directly scalable: You may find that you can scale it to the faux book dimensions. I bought the book first and designed the insert to fit. best of luck should you choose to follow this path.

The clip file is used to hold the book cover up and just slides over the cover and the edge of the dice tower

The drawer is held in place by 4 1/8in x 1/8in cylinder magnets

Tower stand is hot-glued to inside of box edge and the tower slides on snugly. Care must be taken to disassemble so as not to pull the stand off the box

Drawer files (2) are flexible in design one is just a big open area, the other was customized for some minis and dice.

Artwork is obviously to the user's choice and discretion. No artwork is provided for obvious reasons. 

When broken down the tower fits cleanly and has room for plenty of dice, a few miniatures, etc.
