Magazine / brochure notebook holder

This was a really quick design, perfect for 3D printing. We have some booklets that are too small to stand up on a shelf on their own, and it would be great to stick them in a notebook. Imagine something that was printed on 11"x17" paper and then staple-bound in the middle to make an 8.5"x11" booklet. My wife was familiar with a product made for holding magazines or brochures in a notebook, and found and example on line. A simple sketch-extrude project in Fusion 360. I designed and printed one, then decided we could print it thinner and make some cutouts to save time and plastic.

Only one problem: this would push the limits of the bed on my Robo3D R1+, and as I've written before, the far edges of the bed don't heat well. That could cause ends to curl or cause the whole thing to come loose. So as I did with the Face Mask project, I created little "brims" which make the narrow ends a little bigger. With more surface area, ends stick better. I make them as independent parts, and then drag and rotate them into place on the virtual bed so they *just* contact the model. 

This results in narrow joints that snap off easily.

Here's the product in real life. It prints in 20 minutes and costs 19 cents to make.

And how it works in the notebook.
