🐊 Alligator Page Holder

by Essex Labs

Designed by Sean Essex

Hold your book open comfortably with just one hand.

This alligator-shaped thumb page holder keeps your pages spread while you read—just slide your thumb through the center hole and let the gator do the work.

It works especially well for paperbacks that tend to close on their own, but it’s also useful for most hardcover books.

Designed for fast, easy 3D printing, you can have a finished print in under 30 minutes.
