RAINBOX is a playful yet practical 3D-printable design that combines a colorful bookend with a smart storage solution. Designed to rotate, open, and lock securely, RAINBOX adapts easily between a sturdy book support and a compact desk organizer.

When opened, RAINBOX reveals multiple internal compartments—perfect for storing markers, pens, bookmarks, sticky notes, and other small desk essentials. The two halves rotate smoothly and connect firmly using 6×3 magnets, allowing a satisfying open-and-close motion while keeping everything neatly in place.

Whether you use it on a bookshelf, a desk, or in a creative workspace, RAINBOX adds both functionality and personality to your setup.
