It’s just an ordinary piece of cardboard, but it can be played so “thrillingly”!
Fold the rectangular cardboard in half, draw a circle of squares in the middle, and cut it with a knife. You can create a 3D dynamic rotation effect by opening and closing the card.
As long as you strictly follow the steps to achieve the artistic beauty of a delicate mechanism, even a handicapped person can do it, come and try it~
First submit the drawing, which consists of 7 gradually smaller squares.
The black line in the picture must be cut, but the red and green lines must not be cut.
Use a knife and ruler to cut the black line. The line must be straight.
Remember to pad it to prevent scratching the desktop.
The black lines of all 7 boxes are drawn, and the upper part is operated first.
Fold the vertical red line on the upper part, as shown in the picture.
Next, process the second half, the same operation.
Cut out the black line in the lower half and fold the vertical green line.
Next, fold each square outward or inward.
Refer to the picture above, fold the green connecting line outward and the red connecting line inward.
At this point, a 3D rotating structure is completed.
Slowly open it and you will see the effect of continuous rotation.
You can use this when making greeting cards next time~
