3D Printed Thumb Book Holder

When I saw these nifty thumb book page holders available to print, they looked like a simple and useful project. 

I used some black PLA on our printer with standard settings (.2 resolution, 20% infil).

The first one came out a bit stringy, but otherwise perfect. It printed in about 30 minutes, so I printed a second one.

Now I have two of these lovely book page holders!
