| Text | This box model is known in Japan as Masu. Two variations in the folding method create a lid and partitions that divide the box into four compartments. There is even a lid variant to top the box. By playing with the colors of the three components, we obtain a lot of variation possibilities.
a - Bottom of the box 1. Make a blintz base, hold it in a horizontal position, the four triangular flaps on top. 2. Create a valley fold by bringing the upper edge to the lower edge from top to bottom. We obtain a rectangular shape with a hinge fold at the top which connects two flaps of double thickness. 3. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap on the hinge fold. 4. Flip the fold from right to left. 5. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap on the hinge fold. 6. Unfold to return to the lined base. The two triangular flaps at the top and bottom have a horizontal mountain fold in the middle. 7. Fold, from bottom to top, the tip of the upper triangle under the top of the triangle, using the mountain fold which divides it in two. 8. Fold, from top to bottom, the tip of the lower triangle under the bottom of the triangle, using the mountain fold which divides it in two. The two single-thickness triangular flaps are replaced by two double-thick trapezoid-shaped flaps. 9. Rotate the fold 90 degrees. We will repeat the operations from step 2 to step 8 in the new folding orientation. 10. Create a valley fold by bringing the top edge to the bottom edge from top to bottom. We obtain a rectangular shape with a hinge fold at the top which connects two flaps of double thickness. 11. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap on the hinge fold. 12. Flip the fold from right to left. 13. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap on the hinge fold. 14. Unfold to return to the lined base. The two triangular flaps at the top and bottom have a horizontal mountain fold in the middle. 15. Fold, from bottom to top, the tip of the upper triangle under the top of the triangle, using the mountain fold which divides it in two. 16. Fold, from top to bottom, the tip of the lower triangle under the bottom of the triangle, using the mountain fold which divides it in two. We have a square shape in a horizontal position which has, on each of its sides, a double-thick trapezoidal flap. The trapezoids join two by two at their oblique sides. The short sides parallel to the edges draw a square inside the shape. 17. Create a valley fold by bringing, from top to bottom, the upper edge to the lower edge. The fold already exists. 18. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap on the hinge fold. 19. Flip the fold from right to left. 20. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap on the hinge fold. We have a rectangular shape which hides a small 4-ply accordion. At the top, the accordion forms three flaps. At the bottom, there are only two quadruple thick flaps. 21. Open the folding by unfolding the two lower flaps. We obtain a rectangular shape which has two rectangular flaps located on either side of the horizontal median. Each rectangular flap carries a trapezoidal flap of double thickness which hides a small triangular flap. 22. Fold the upper trapezoidal flap downwards. This operation clears the two upper left and right corners. Each corner has a small triangle which forms a sort of pocket. The entrance to the pocket is an oblique edge. 23. Using the oblique edge of the upper left triangle, create an oblique valley fold, folding from left to right. Mark the fold well. 24. Using the oblique edge of the upper right triangle, create an oblique valley fold, folding from right to left. Mark the fold well. 25. Fold the trapezoidal flap upwards, leaving the small triangle hidden underneath. This sequence of operations allows you to block the corners under the flap. 26. Rotate the fold 180 degrees to bring the bottom side up. We will restart the operations from step a-22 to step a-25. 27. Fold the upper trapezoidal flap downwards. This operation clears the two upper left and right corners. Each corner has a small triangle which forms a sort of pocket. The entrance to the pocket is an oblique edge. 28. Using the oblique edge of the upper left triangle, create an oblique valley fold, folding from left to right. Mark the fold well. 29. Using the oblique edge of the upper right triangle, create an oblique valley fold, folding from right to left. Mark the fold well. 30. Fold the trapezoidal flap upwards, leaving the small triangle hidden underneath. We have a hexagonal shape with a left tip and a right tip connected by a square. The horizontal median has an opening which goes from the top of the left point to the top of the right point. 31. Insert fingers into opening and open box. The two points go up vertically. 32. Mark the vertical edges of the box by pinching them. The bottom of the box is finished. All that remains is to complete the work with a lid and separations. b - Lid The construction of a cover is very simple. We use the same sequence of folds, with two modifications in the way of proceeding. 1. Take a sheet of paper of the same dimensions as that used to create the background. Start at step a-1. 2. During step a-3, instead of folding the lower edge to the upper edge, we stop a few millimeters before this edge. The bottom will widen accordingly. 3. During step a-5, in order to respect the symmetry of the folds, fold the lower edge, aligning with the fold made in step 2. Replaced instructions from step a-10 to step a-16. 4. Flatten the upper triangular flap by rotating it, from bottom to top, around the hinge fold forming its upper side. The hinge fold has become a valley fold. From the left and right vertices forming the ends of this valley fold, two oblique edges extend towards the interior of the shape. These oblique edges are continued by two vertical edges. Locate the two vertices which mark the change of direction. 5. Create a mountain fold passing through the two peaks marking the change in direction of the oblique edges starting from the ends of the upper valley fold. 6. Return the triangular flap to its starting position in the lined base. 7. Using the mountain fold made in step 4, mark the point of the triangle. Unfold. 8. Slide the tip of the triangle under the trapezoidal flap. All these operations make it possible to obtain a trapezoidal flap of the same size as the two vertical flaps. 9. Rotate the fold 180 degrees, to bring the top edge up. 10. Flatten the upper triangular flap by rotating it, from bottom to top, around the hinge fold forming its upper side. The hinge fold has become a valley fold. From the left and right vertices forming the ends of this valley fold, two oblique edges extend towards the interior of the shape. These oblique edges are continued by two vertical edges. Locate the two vertices which mark the change of direction. 11. Create a mountain fold passing through the two peaks marking the change in direction of the oblique edges starting from the ends of the upper valley fold. 12. Return the triangular flap to its starting position in the lined base. 13. Using the mountain fold made in step 11, mark the point of the triangle. Unfold. 14. Slide the tip of the triangle under the trapezoidal flap. We have a square shape in a horizontal position which has, on each of its sides, a double-thick trapezoidal flap. The trapezoids join two by two at their oblique sides. The short sides parallel to the edges draw a square inside the shape. 15. Resume the usual folding sequence in step a-17. The edges of the opening will no longer be joined, but will be separated by an interval corresponding to the difference in width between the bottom and the lid of the box. All you have to do is fit one into the other. c - Partitioning Creating the partitioning is also very simple. We start by folding a background identical to the one already made, then we finish with two manipulations which transform this background into a partition. 1. Take a sheet of paper of the same dimensions as that used to create the background. Create a new box bottom identical to the first. Two opposite sides are smooth, two other opposite sides have small excess triangles. 2. Hold the bottom of the box so that the smooth sides are horizontal. Place your right thumb on the right side, outside. Place the left thumb on the left side, outside. Slide the middle finger of your right hand under the box, so you can push up into the center of the bottom. 3. Simultaneously, push both thumbs inward and middle fingers upward. The box folds in on itself and transforms into four partitions radiating from the center. All that remains is to arrange this partitioning, either on the medians or on the diagonals of the bottom. And there you go ! d - Variant: crown cover The process closely resembles making the bottom of a box. 1. Make a blintz base, hold it in a horizontal position, the four triangular flaps on top. 2. Create a valley fold by bringing the upper edge to the lower edge from top to bottom. We obtain a rectangular shape with a hinge fold at the top which connects two flaps of double thickness. 3. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap a few millimeters from the hinge fold. Caution: do not fold the triangular tip, but let it come back outwards. 4. Flip the fold from right to left. 5. Create a valley fold by bringing, from bottom to top, the lower edge of the upper flap a few millimeters from the hinge fold. Caution: do not fold the triangular tip, but let it come back outwards. We have a rectangular shape with two triangular flaps at the front and rear facing downwards and which protrude from the rectangle. 6. Open the folding by unfolding the two lower flaps. We obtain a rectangular shape which has two rectangular flaps located on either side of the horizontal median. Each rectangular flap carries a triangular flap of simple thickness which protrudes from the rectangle. 7. Repeat the usual operations of making a background from step a-22 to step a-32 |
