book holder

This 3D-printed book holder is a compact and practical reading accessory designed to keep pages open with minimal effort. It fits comfortably over the thumb, using a smooth curved inner channel for a secure and ergonomic grip. The wide outer wings gently press down both pages, preventing them from flipping while reading with one hand. Its lightweight yet sturdy construction makes it ideal for long reading sessions, whether at home, on the go, or while multitasking. The bright color and simple geometric design give it a modern, functional look that pairs well with everyday use.
