Get at least three SNUDDA lazy Susans to create multiple tiers so there's space for housing multiple books, especially since the wooden dividers add four sections to each tier.
Add two more wooden boards on both sides using a drill and some screws to keep the boards in place, which will give your bookcase the dividers it needs to create sections.
Place another lazy Susan on top and repeat this process. For extra style and security, add wooden bookends to the edge of the sections to keep the books in place.
Use your glue to draw a line on one side of the bookend to keep it locked on the board. You can further paint and decorate your bookshelf for more style and personal touch.
