I was looking for a balance between size, security and easily displaying colors. In addition to the possibility of slightly customizing and carrying other extra samples such as text, infill and others also in the same box.

So I made some small modifications and surely in the future I will adapt even more for greater versatility since I would like to have some wider samples, more space, double or triple.

You only need 6 M3x30 screws. I personally used these.

In this other adaptation of mine it has the swatches that I print.
