这就是 600 年前中国明朝永乐大帝的御用宝剑永乐剑，
我们根据图片将它复刻成了可以 3d 打印的伸缩剑玩具，因为伸缩剑比较容易损毁，所以设计成了可以替换的模式。
希望漂泊海外的国宝早日回家！

需要 4 个 M2*6 的沉头螺丝

This is the Yongle Sword, a treasured weapon once used by the Emperor Yongle of the Ming Dynasty in China 600 years ago. Now, it has been lost overseas 

We have recreated it into a collapsible sword toy that can be 3D printed, based on the images. As collapsible swords are prone to damage, we designed it with a replaceable mechanism.

we hope that the national treasures drifting overseas will return home soon!

We need four countersunk screws M2*6
