I lost my luggage during my last plane journey.
It took 2 month and a lot of work to find my luggage because there was no tag on my luggage. (I'm a complete idiot).
So I did this simple engraved tag and put it on all my luggage.

Engraved tag cannot be erased and last longer.
Printed with gold filament It look cool on my luggage :-)
And I'm sure I will recognize my luggage now.

The STL is not intended to be printed directly (unless your name is Bob Squarepants).
You must edit the openscad script.

You can customize it with your name, phone number & email address.
Or whatever you want to write on it. There is three text lines.

To customize it:
1) You will need openscad software on your computer : https://www.openscad.org/
2) Open the luggage_tag_bob.scad file in openscad.
3) change the "line=" variable with your own text
4) F5 for a quick verification, F6 to render the shape, F7 to save the STL.

rendering can be slow (about 12mn).

if you ever try to print it in metal, send me a picture.
