Book thing helps you hold a book's pages open when holding it in one hand. This works two ways:

1. On your thumb when holding the bottom of the book, or 
2. On your index finger when holding the top of the book.

Book Thing V2 is now double-sided with different curves on each side so it fits more comfortably on books of different thicknesses.

V2 also improves by about 10% on the original by using less filament and printing faster. 

The first Book Thing model I uploaded was one of my first 3D model designs, and I have been blown away by how popular it has become. Thank you to everyone who took the time to like, rate, comment, and make it!

Don't hesitate to contact me about licensing if you want to sell physical prints! I have licensed the original model for free to small businesses to sell prints in limited quantities.
