The tutorial for folding Luban locks with paper money is actually very simple, but some beginners still can't understand it. This actual shot emphasizes the key parts, and I hope everyone can learn it. One yuan is special, not a 2:1 ratio, but it also has its benefits.
The following is a real shot using one yuan as an example to start. Fold the long side in half.
Measure 13x3=39mm from the middle crease to one side and fold the crease.
Bills are turned over. The length of the short side of one yuan is 63mm and should not be divided into five equal parts. Because some of it needs to be collected inside, four equal parts are enough. Then measure the position of 13x4=52mm and divide it into four equal parts. The remaining 10mm is the part hidden inside.
At the beginning, divide it into three equal parts between the two vertical creases, making sure to leave only the crease in the middle part. The location of the tutorial map is visible.
Fold out four hypotenuses. See tutorial location.
Fold the outer sides. Fold it into an L shape, please refer to the tutorial picture.
Connect the two and plug them in. Make three. The following is all about being careful and patient. complete.
