I. CREATION OF THE MATRIX FOR THE "STRUCTURE" AND THE "SCREEN"
a. A 21 cm base cardboard-matrix for 24 cm height is prepared, which folds twice and is then reopened.
b. Operating on the top left corner of the cardboard-matrix, we must identify six points, at which holes will subsequently be drilled: four points must be 1.5 cm distant from the left lateral edge and distant from the upper edge, respectively, 1.5 cm, 5 cm, 7 cm and cm 9; two other points must be 1.5 cm away from the upper edge and 4.5 cm and 8.5 cm away from the left side edge respectively.
c. This identification, of course, could be done by operating on the cardboard-matrix with a common row, instead we will do it using the particular row that we have prepared: the multifunctional Ruler.
d. Operating on the top left corner of the cardboard-matrix, we superimpose the multifunctional ruler vertically on it, starting from its ALFA end.
e. Through the four holes on the multifunctional Ruler, we draw the first four rods on the cardboard-matrix.
f. Operating again on the top left corner of the cardboard-matrix, we superimpose the multifunctional ruler horizontally, starting from its BETA end.
g. Through the first and third of the four holes on the multifunctional Ruler, we draw two more rods on the cardboard-matrix.
h. We have obtained six rods in all.
i. The cardboard-matrix is folded twice, so as to obtain four quadrants and in such a way that the quadrant on which we have identified the six points for drilling are visible.
j. The drilling is carried out, involving in the drilling all the four layers which were formed in the cardboard-matrix by the effect of the folds, and thus we obtain the twenty-four holes that will be involved in the packaging of the mask.
k. The twenty-four holes are distributed six to six on the four quadrants that formed in the folds of the cardboard-matrix, and it appears that the holes of the first quadrant are symmetrical to the holes of the second quadrant, and that the holes of the first and second quadrant together, are symmetrical to the holes of the third and fourth quadrant together.
l. The points of the first quadrant are marked with the letters from A1 to F1, the points of the second quadrant are marked with the letters from A2 to F2, the points of the third quadrant are marked with the letters from A3 to F3, the points of the fourth quadrant are marked with the letters from A4 to F4.
m. The Matrix of the Structure Form and of the Screen Form is ready.
