Filament Identification Tags

I use a lot of Masterspool stuff where it may not be easy to identify what a filament is once it isn't on a spool. I designed these so I can slip them over the end of either a 3mm or 1.75mm filament end and identify the material at a glance.

Designed for easy multiple color filament swap printing. Embossed and inset versions to satisfy even the pickiest of nerds.
