The MultiStorage mod adds new ender chests. Experienced fans are well aware that this is the right thing for the cube adventure.

Here you will add 15 ender chests and new bags that you can carry and store things in them, and the coolest chest will be a chameleon, near which block you put it, after which it will be the same shape, and to open the chameleon chest you need to hold down the button "Shift", you can still make a safe that only you can open and when you build from special blocks the structure can not be destroyed even in creative mode.
