In this short tutorial, I show you guys how to create your very own Minecraft Bank Vault/Safe/Piston door. It is a 3x3x3 door, and looks very, very secure. Although it does not have the middle blocks. This is due to the fact to keep the aesthetics of the door looking better than the functionality of the door. So you could technically enderpearl through it. It is mainly supposed to be used for Adventure maps/singleplayer worlds/machinimas, something where you just want a nice looking, working, awesome vault door.
