I wanted a luggage tag that would be a little more discreet than the usual "business card" ones. It seems like a phone number is all you need, that and the kindness of a stranger. I guess you could put other info on it if it will fit! Use the customizer. Don't bother to download the stl file unless your phone number is 800-555-1234. ;) Also, after you "Create Thing" be sure to uncheck the "Publish New Thing" box.
