The small ellipse in front can be used to signal a filament color change.
It is one layer taller than the large ellipse around the tag .
If you watch the printer head when it no longer goes to the small ellipse it's safe to change without laying any of the first color on the 4mm high outer ellipse.
If you start with a dark color like black and then change to Glow-in-the-dark filament the name will seem to float when in the dark.

Add a metal split ring to attach keys or to attach the tag to a book bag zipper pull.
