Simple course of manual carton

The simple tutorial of manual paper box is as follows:

Materials and tools: paper, scissors.

Step 1: First, we prepare a piece of paper, which must be square. We walk along the diagonal once and the two opposite sides of the square fold once. As shown in the figure below:

Step 2: Then we find a quarter of the square. We fold this corner of the square in the center of the square and pay attention to the alignment of the sides. As shown in the figure below:

Step 3: Then fold the remaining three vertices in half according to the method in step 2, as shown in the following figure:

Step 4: Next, we fold the two sides of the square in the middle according to the direction shown in the diagram, as shown below:

Step 5: The folded paper style is as shown in the figure below, and then we fold the paper inward according to the arrow direction in the figure. As shown in the figure below:

Step 6: Finally, we fold the paper into the shape shown below.

Step 7: Then, we expand it, as shown in the following figure:

Step 8: Start folding both sides of the carton, as shown in the figure. One side is divided into three parts, the small square in the middle is the lower part, the triangle on one side is divided into three parts by two creases, and the part closest to the small square is the erected frame, as shown in the figure below:

Step 9: Then we slowly lift the triangle and nest its sides inward, as shown in the following figure:

Step 10: When we finish Step 9, we finally turn the paper box upside down, so that a simple paper box is finished. As shown in the figure below:
