I designed this elegant bone dog tag based on previous designs that I saw in Thingiverse but that were too "plain" to my taste.

The size of the tag is configurable along with the number of lines to print.

The molding around the bone can be set or not (just comment out the line if not needed).

Also, the design accommodates for dual-extruder printers so that the base bone tag can be printed in one color and the in-print + molding with another color.

Happy to hear from anyone's comment or suggestions for improvements.
Enjoy!
