Infinitely expandable storage cubes Free 3D print model

One problem I always run into is finding storage space. Yes you could go out and buy a shelf. But its no fun when you cannot expand without going and buying another shelf for $30 to $50, that isn't able to be re-arranged or shaped how you want it when you want it. Oh and did I mention that its free? I hope you enjoy your new storage spaces! Cubes are 5,5,5 in
