I love and find really great and useful Filament Swatches, so I printed the Swatch Display Board by Bambu Lab

The problem I had was that, when I wasn't using the Boards, I had them scattered around.
So I could loose them, or ruin them, since my work bench is always full of tools.

There are many projects to display the swatches, but I prefer to have them in a drawer, ready for when I need them.
So I designed a little gridfinity box that can hold up to 7 different boards (140 total swatches).

I included a small hole so I can use my finger to easily grab any board, even the bottom one.
It's a simple design and I didn't need anything else, but I'm open to suggestion, if anyone thinks it can be improved.
