If you are like me, having a lot of filament of different material and colour and different manufacture, then you want to have a little sample like this, to show your clients if they need to chose a colour from or any material or so...
This is a nice mode of presenting it.
The design is made by 2 parts:
The Body & the Cover
You can print the label (file number 5) then cut off the sheet of paper to the size of the label.
Then you can attach to the body and write the material and colour code.
If you wanna be fancy like me, you can make a graphic as I did and colour print it after cut it.
