Engineering Journal Pencil Clip

I really like the feel of using a pencil and my handwriting is better when I use a 0.5mm mechanical pencil.  Given that I need to go back a read what I write in my engineering notebook, I spent a bit extra to get a really nice Kaweco mechanical pencil that can fit in my pocket.  I of course needed a pocket sized journal and some way of keeping the two together.   So, I designed this two part clip that slides into the spine of these pocket sized notebooks to keep them together and my pencil from getting misplaced and lost.  Seems super niche but maybe someone else out there could use it.   Links to the products that I used are below.  The amazon links are just for convenience (not affiliate links), feel free to get them wherever you can.
