Thanks to Nishi Sakpal for helping with the refinement of the folding sequence, which helped to eliminate extra/unnecessary steps.
Paper to be used: 3 squares for the box and 3 squares for the lid.
Thicker paper or thin cardstock is recommended.
Folding level: Beginner to Intermediate
Steps: 19
Description: This is a modular origami model, meaning that it is made up of different, similar folded units, which are fitted together to form the finished model.
The model is a triangular box with a separate lid. The outside of the box is smooth except for 3 small triangles that are visible on each of the 3 corners.
The bottom of the box is made up of 3 triangles that overlap each other, with two of them forming a lock to keep the bottom in place.
A lid can be created by folding 3 more squares and assembling the bottom and lid of the box separately. See Step 19 for more information.
When you have become familiar with assembling the units, you might like to try and use more than one color when designing your modular box and/or lid.
Keep in mind that although this model is fairly secure, its base is made up of different units, so it will not be as strong as a box folded from a single sheet of paper.
You might want to secure the bottom of this box for durability's sake, either by using tape or glue or by adding an extra folded or cut triangular base placed on the inside or outside of the folded model.
This is optional, though.
PHASE 1: CREATING THE UNITS:
You will be folding 3 similar units to form your box.
It is recommended that you fold all 3 pieces before attempting Phase 3, which will explain how to fit the pieces together to form the finished model.
If using two-sided origami paper, lay your paper with the patterned or colored side down before starting to fold.
Step 1
Place a square down with its edges to the left and right, top and bottom.
Step 2
Fold the top edge down to meet the bottom edge. Crease and unfold.
Step 3
Fold the bottom edge up to meet the center crease.
Crease and unfold.
Result: Your square will now have two horizontal crease lines.
Focus on the horizontal line nearest you. We will call this Line A.
Step 4
Take the top left corner of the square and fold it diagonally down so the left edge meets Line A.
Make a strong crease and leave folded.
Result: There will be a triangle on the left now.
Step 5
Now, do the same with the top right corner, also bringing it down so the right edge meets Line A.
Result: The right triangle that you will create will fold on top of the already folded left triangle.
Step 6
Refold over the bottom edge along Line A, so that the bottom rectangle will cover the bottom part of the triangle.
Step 7
Fold down the top corner of the triangle so it meets the bottom center point of the shape.
Crease well and leave folded.
Step 8
Take both the left and right edges of the rectangle and fold them straight over so they meet each other at the center of the figure.
Result: You now have a multi-layered flat rectangle again.
The back of it is smooth with the point of the large triangle hiding inside the shape.
On the front there should be two squares made up of single layers that touch each other along the horizontal center of the rectangle.
There will also be two small triangles that have formed, one on the bottom left and one on the bottom right corners of each square.
Step 9
Still keeping the model flat, rotate the rectangle 180 degrees so the triangles are at the top left and right corners.
Step 10
Unfold the left and right squares and also the large triangle, but do not press them flat.
Let them stand up at a 90 degree angle in relation to your folding surface.
Result: Nearest you will be the large triangle with the square flaps on the left and right.
Behind the triangle there will still be The smooth rectangle that will be flat on the table.
Step 11
Lastly, flip the unit towards you so that the triangle is flat on the table, nearest you.
The rectangle, that will form the wall of the box, will be upright now, with a square flap on each side of it.
Your first module is done. Set it aside for now.
PHASE 2: FOLD MORE SIMILAR UNITS
Repeat steps 1 to 11 twice more so you have 3 similarly shaped units to work with.
PHASE 3: ASSEMBLING YOUR MODEL
Step 12
Position your 3 units in a loose formation so they represent the three corners of the box. You will have the sides or walls of the units in an upright position with the triangles that will form the bottom of the box , flat on the table.
Step 13
Explanation
Concentrate on the outer sides or walls of your box. They are made up of two layers, forming pockets, with flaps on the inside that can be lifted.
You will be starting with the two units furthest away from you. Mentally number the unit on the left as unit 1 and unit 2 will be on the right.
Step 14
Place the second unit's side flap under the side flap of the first.
Hold the two units in a straight line and push them together so the triangular bases are close together, but do not yet overlap.
Use the left and right square flaps as your reference here, only sliding unit 2 under the flap of unit 1 until its square flap is hidden. Once the modules are brought together, the square flaps will act as hooks to keep your modules in place.
Step 15
Repeat Step 14 so units 2 and 3 are connected in the same way.
Step 16
Lastly, press the units closer together and slide in the third unit's side flap under the first, thus closing the triangular shape.
The 3 triangles that make up the bottom of the box will have moved to lie on top of each other now.
Step 17
Flip the box over and insert one of the triangles into the pocket formed by the one next to it.
Step 18
Make sure the third triangle lies on the inside of the box.
Also, check that the 3 corner triangles of your box all look similar. They should all face in the same direction.
Step 19
To make a lid, try to create a small space between the folded band at the bottom of the model and the folded-down triangles.
This should be enough to ensure that the lid is just slightly bigger than the base of the box.
