Spiral Notebook Protector

My son-in-law is a deputy sheriff and asked if I could create a cover for his notebook because it always gets frayed from excessive use (in and out of his molle vest pockets). I also work in the legal field and have had similar problems with notebooks fraying or getting messed up before the end of their lifespan. I looked around and tried to locate another design but it did not work so as I've said before, created the attached files out of necessity. The smaller cover is for a 3x5 notebook and the other 2 are for a 4x8 notebook but with a different hole count. I use TPU for its durability. I printed a 2mm thick because thinner was easy to tear and thicker was too rigid. I also printed it on a carbon fiber plate to give it the cool look that you see in the photos. I made it so that you could just lay it on top of the notebook and press it between the spiral notebook wire. You may have to cut the slits or pull them apart so that it will fit on the notebook more easily. I and my son h
