This elegant bookend is designed as a standing shell, perfect for supporting books on shelves or desks. The visible part features a hollow shell, reducing material use and printing time, while allowing you to fill it with sand, small stones, or any weighted material for stability. The base extends under the last book, using the weight of your books as leverage to keep the shell upright. The back is smooth and has a small hole for filling, which can be sealed with the included cover once filled. Its minimalist, functional design combines aesthetics with practicality, and the concept of filling the shell with natural elements adds a tactile, meaningful touch.
