Here is video demonstration of GCodePrintr interacting with NFC tags embedded in 3d printed objects. After the near contact the NFC tag emits link to URL that loads remote g code of the object in the software and you can print new copy.
Simply, you touch an object and you can print it using your smartphone.
I could see many use cases, like consumer goods where you can print simple replacement parts like handles etc. by scanning the NFC tag embedded in them.
