Christmas day - my daughter closes the car door on her coat which has her cell phone in the pocket. This kills the phone. I happen to have an slightly older unlocked phone that I use less than once per month so we simply swap SIM cards right? - but the cards are not compatible. She has a Micro SIM card and I have a Mini SIM card. It is Christmas Day, so no stores are open to buy an adapter. But Wait, I'm just road testing a Cel Robox 3D printer - why not print off an adapter. Great - 3 minutes later I have clear PLA micro to mini adapter and instantly the old phone has all my daughter's contacts in it....how cool is that? - awesome.
So suddenly everyone is a big fan of the new 3D printer.
Merry Christmas is back on!
