The keys to the submarine

thingiverse

There's this practical joke where you wake someone up in the middle of the night yelling "WHERE ARE THE KEYS TO THE SUBMARINE?!!" to confuse a sleeping person and see their reaction. I came up with a response to this prank: If you have an old key that you don't know what it's for (I found the key pictured on the ground a few years ago and kept it), you can print this keychain for it and hide it someplace random, the third cupboard to the left in the kitchen for example, and if someone ever does this prank to you you can direct them to its location. They will think that they have made you look dumb half sleeping, but you can just repeat your answer and for the chance that someone goes to check, that's what it's for. It's a very specific item to have but you gotta be ready! Or maybe you do just have the keys to the submarine, in which case it's a nice accessory to have. 45.6mm*31.7mm*2.9mm in size and 0.073% chance of being used
