Simple idea of making a book like storage bin where you can put a 3 by 5 Gridfinity base board. The idea was to put whatever type of storage you want especially modular like Gridfinity while having the discreet look of a book. I mainly did this so the tools and other parts that came with my P1S could be put away on my bookshelf and it would just look like the rest of the books and not look like random tools on a desk.

Recommendation when assembling the book cover to the base you can use filament from a spool and cut it, but it works a lot better if you use a metal pin roughly the same diameter as the Allen wrenches that come with your 3d printer.
