The rectangular box by Clemente Giusto, featured in an article a couple of months ago, has similarities to a square-based box diagrammed in Florence Temko's book Origami Boxes and More (Tuttle, 2004). (The domed box made from daisy flowered paper is the model shown in Tempko's book.) Both boxes have double layered roof sections. In both boxes paper strips are "woven" across the lower roof to form the upper roof.
Similarities in origami are common. Many would-be origami artist has been irritated to discover that the creation they have just proudly designed has merely reinvented an origami wheel.
The problem with both the Giusto box and the Temko box is that the walls are relatively weak compared to the roof sections. This can result in wall collapse during construction.
Yami Yamauchi solves this problem by placing an acrylic block in the center of the pre-creased paper so that he can support the walls around it and squash the roof sections firmly on it. The problem with that solution is that you either have to make all your boxes the same size or you have to cut a new block every time you want to make a box of a different size.
My solution to the Giusto box has already been documented in a previous blog. My solution to Florence's box was to add a simple double thickness box in the center.
I also redesigned the external roof section so that it avoided the central hole and folded down flat. In order to achieve that purpose the ends of the protruding strips are tucked inwards.
The variation, showing the color on the back of the sheet, was achieved by turning a larger section of each corner under. A look at the Crease Patterns and a consideration of the photos showing how the boxes open up should explain the differences.
If you make this box from the crease patterns provided here, start the internal box by dividing the paper into an 8 x 8 grid with two diagonals. Then bring the corner points into the center (blintz). Proceed by folding the model according to the crease pattern shown in the central diamond. During assembly the walls are folded over each other from left to right all the way around. The last wall needs to be lifted so that the corner section can be tucked to continue the pattern of its neighbours.
Although this makes a box with walls that are thicker on the left half than the right half of each side this is disguised by the decorative outer shell.
