I wasn't satisfied with the filament samples I saw around, they were either too large, too simple, or boring. This is my version of filament samples shaped like floppy disks, with gradients for transparency. I also designed the labels which you can find in PDF format. Print them on adhesive paper, or normal paper and then cut them out and stick them on the mini floppy disks.
In the 3mf version, you will find 4 separate mini floppy disks to be printed one at a time with 4 different filaments.
