This is an easy 5mm thick Print-In-Place Field notes cover for 5.5x3.5 field note books.
I use them on a daily, and this is a great way to keep your notes protected and intact.
This is version 2, the first version was not PIP and was a little harder for people to make as it required hardware.
This one requires only the either gluing or melting of the field note book cover clamps.
It is a .3mf file, and may need to be CTRL+Z to get it to sit properly in your slicer. I use CURA.
