Paper to be used: 2 squares of the same size.
Difficulty: Easy.
The modules are very simple and the insertion is very intuitive.
Description:
It is a tetrahedron or triangular pyramid, which means it has 4 triangular faces that are all the same size.
The final piece is completely closed, except for a slot that can be carefully opened to fit small objects into its hollow interior.
To keep this slot open you have to hold it, so when you release it you cannot see the inside of the box, useful for hiding a surprise gift inside.
*Clarification:
Unlike many other modular pieces that have several exactly the same modules, this box has two slightly different modules that we will call module 1 and module 2.
I recommend reading the steps and the final description of each one carefully when folding, to avoid confusion.
Shall we start?
(A) Creation of module 1:
First we must make a kite base.
If you know how to do this without instructions, you can skip directly to the figure description that comes after step 4.
The beginning of this description is marked by 3 asterisks.
Step 1:
Place the first square on our work surface in the diamond orientation or with the 4 points facing up and down, left and right.
When the box is complete, only the side of the paper that we left face down in this step will be visible.
Step 2:
ring the left point towards the right point, forming a triangle.
Crease and unfold.
Now, our rhombus will be divided into 2 large triangles by a central line that goes from the top point to the bottom point.
Step 3:
Bring the lower left edge of the figure towards the center line. We will generate an acute triangle that is located at the bottom left of the rhombus.
Step 4:
Repeat Step 3 with the bottom right edge, so that the newly folded edges are now touching the vertical center line.
***The result is the Kite Base, which could be divided into two parts:
Sometimes I like to compare it to an ice cream cone, where the cone is made up of the two sharp triangles generated in steps 3 and 4, which have a total of two layers of paper, and the ice cream scoop is the smaller, wider triangle remaining, that has only one layer of paper.
For the next step, we will orient the figure with the sharp tip of the cone towards us and the ice cream scoop facing away from us.
Step 5:
Our ice cream ball is separated from the cone by a straight horizontal line that runs from left to right across the width of the Kite Base.
We are going to take the scoop of ice cream towards the cone, folding exactly along the separation line that I just described.
The result will be a triangle that retains the shape of the cone but without its ice cream.
In other words, it is an elongated triangle with its sharpest point facing us, while the shorter flat side,formed by the last fold, is facing away from us.
Step 6
There is a vertical line that divides the figure in half.
It is formed by the central slot. Even where the ice cream I described in step 5 covers the slot, the first diagonal fold we made in step 2 still marks this center line.
Using this as a reference point, we'll bring the bottom sharp point of the triangle to the exact center of the top edge.
As a result, we will have a trapezoid with its shortest side being the last fold we made.
On top of this four-sided shape, is the triangle that we just created and that we will use as a reference for the next two steps.
Step 7:
The triangle mentioned above is formed by the following lines:
*The last fold made, which forms the bottom edge of the triangle.
*A fold that goes from the center of the upper edge to the right bottom corner.
*A fold identical to the previous one that goes from the center of the upper edge to the left bottom corner.
This step consists of bringing the top right tip of the trapezoid downwards and towards the left.
The fold made has to exactly follow the right edge of the triangle I just described.
Crease and unfold.
Step 8:
Repeat this last step, bringing the top left tip of the trapezoid downwards and towards the right, this time following the left edge of the central triangle.
Crease and unfold.
Step 9:
Module 1 is finished.
Now we can present it in the form of a pyramid, which will show us the final size of the box.
The base of the pyramid will be the central triangle, now flat on the table.
Around the base, you will find its 3 triangular walls or fins.
The only thing left is to raise these walls so that the points of these triangles will touch each other at the top of the pyramid.
I know it's not a solid figure yet, but it helps us understand the size and shape of the final product.
(B) Creation of module 2:
Step 1:
Follow Steps 1 to 5 described for module 1, so that we have an elongated triangle with its sharp point facing us.
From here on, there will be slight changes that will make module 2 look different.
Step 2:
Flip the paper from left to right as if we were turning the page of a book.
The now-visible face of the figure will be smooth, except for the center crease line we created in Step 2 in Section A above.
Step 3:
Using the center crease as a reference, bring the sharp point to the center of the top edge.
We will obtain a trapezoid as in module 1, with the difference being that the central fold is now covered by a small triangle divided in half by a slot.
Step 4:
Following the left and right edges of this triangle, we will take the two upper points of the trapezoid towards its opposite edges as we also did for module 1.
Before unfolding, we can feel that, on the surface of each of the newly created triangles, there is a pocket with its opening towards us.
Step 5:
Finally we will present the module as we have done before.
If we lift our second pyramid from the work surface and touch its base, we will notice that it has an elongated kite-shaped flap made of a single layer of paper, that will also act as a pocket for the insert.
(C) Before starting the insertion:
I recommend starting to assemble the figure on our work surface, as it is much easier than doing it in the air.
To quickly differentiate module 1 from 2, we will remember that the first is smooth on the outside while the second has pockets on each side.
Keeping module 1 ready, we will let it open slightly to be able to insert a finger inside the pyramid.
When touching the base, we will notice that the same kite-shaped pocket that we have under the base of module 2 is seen, this time on the inside of module 1.
(D) Assembly:
Step 1:
Face the two modules as follows:
We are going to take the kite-shaped pockets as a reference point.
Their openings, which are at the shortest tip of the kites, should be pointing towards each other.
In this way, if we keep the two modules in a pyramid shape, the walls that were previously the sharp tips of our ice cream cones will also face each other.
Module 2 will face with its opening to the left and module 1 with its opening to the right.
Step 2:
Unfold the two fins that are facing each other, so that they are flat.
Step 3:
Insert the left fin of module two into the kite pocket of module 1.
To do this, we will slightly lift this fin and gently guide it towards the pocket so that it slides completely inside it.
Now the two modules are lightly joined by this first locking point that is flat on the table.
We have two pyramids facing each other with a missing wall, separated from each other by a valley fold.
Step 4:
Gently hold the two fins of module 1 in an upright position.
Step 5:
Using the valley fold that separates the two pyramids as a pivot, lift the free pyramid of module 2 and take it to the left.
As a result, the fins of module 2, with their large pockets, will slide so they are almost in between the fins of module 1.
Step 6:
Carefully bend the two fins of module 1 to fully insert them into the triangular pockets of module 2.
Step 7:
Now we only have the kite pocket of module 2, on the left, with its opening pointing diagonally downwards and on the right, the last fin of module 1 that is flat on the table.
We just have to lift the fin up towards the left and insert it completely into the pocket.
Step 8:
Our pyramid box is finished!
The slot to insert objects into it is on the left edge, between the front and rear walls.
We can open it by gently pulling apart these walls
with two fingers, without forcing the paper.
