Hellow my fellow minecraftians! Aidan here, and I know chests do not have enough space. The thought of triple chests always made me happy. Well I was playing with setblock commands, and I happend to be next to my chest when typing the command that saves many's time. Well, if you wanna learn of how to make triple chests with ONE command and two chests, then read this 2 step toturial below!

Step 1: Place 2 chests down anywhere.
Step 2: Be sure that you are next to a chest when performing this command. Step on the left or right, and type this in /setblock ~ ~ ~ chest 
   If you want to disguise the chest, I would make something around it. Be sure to even it, by pretending that there is a chest block where there isn't and building around it, so it looks like the style. This distinguishes the triple chest, and only you would know about it. I hope that helped!
     This will place a invisa chest! Now here is where you must listen. on the side that you placed the chest,  Left for instance, for the glitch to work you MUST click the chest on that side. The chest will open with a little glitched chest at the bottom. You can place blocks in that area, and it has the space of one chest. In the picture, you can see that it is wierd because of the way that it is formated.
