Simple filament swatch with storage

Yet another swatch. I needed a way to discuss different filaments with family and friends for projects I did for them. At first I intended to use @AdamStarbuck's filament swatch card, but I wanted smaller ones, so I recreated them in Blender (the software I am most familiar with). While at it, I also created a Gridfinity (see @ZackFreedman) tray for keeping the swatches in, and a travel box for a small set of filament swatches. It requires 3 M3x30 bolts. I use the slicer to add texts to the swatches.
