King Arthur, after pulling the legendary sword Excalibur from a stone, became king.
Like the kings in other countries, he bought a huge castle.
But what a mess when it was time to go hunting : the keys were always missing !
The poor King looked after them a looooooooong time and when he finally found them and closed his castle's door, the hunt was over.
With this Excalibur key holder, you'll never loose your keys : attach the sword keychain to your keys and the stone to your wall.
When you go back home, plug the sword in the stone on your wall and you'll find them next day !
If King Arthur had asked Merlin to print one, he would have found his keys every time !

Stick the stone to your wall with double faced tape or a screw and plug the sword-keychain you attached to your keys in the little slot on the stone every time you go back home.
That way, your keys will be hanged on your wall.
You can also say you're the True King : in the legend, nobody except him could pull Excalibur from the stone.
Note : I didn't have grey printing filament : I painted the finished object with model paint.
