This model is designed to hold cubic tissue boxes. The tiles can be printed in the original Rubik's cube colors or any other color you want.
The 2 longer tiles from the back and the front need to be placed in the down middle position to hold the bottom piece in place. The tiles with the cutout must be inserted into the appropriate recesses and possibly glued. The remaining tiles can be placed anywhere and exchanged as desired.
