Thank you to https://www.thingiverse.com/thing:858497 for the basic design. I added scroll designs, a hole for a keychain, and beefed up the handle a LOT so it won't break off when being used as a luggage/bag tag. We used Tinkercad to put a name and phone number on the bottom, and then changed filament in the printer after a couple layers to make it more readable.
UPDATE 16 April 2018: uploading a version without the hole
