大家好！
这是我的新作品，叫“Holey Tetrahedron”.第一次尝试了3D打印技术，成品的精度很满意.
此作品虽然是空心结构，不过并非采用冈本先生的Void Cube结构，其实跟Jing’s Pyraminx 一样，也是有弹簧和螺丝的.
详细的内容请看下面附带的照片，希望大家喜欢！

Translate into English:
Hello Guys!
This is my(DDR's) new puzzle, named "Holey Tetrahedron".
It is the first time that I try 3D printing, I am very satisfied with it.
I made this one hollow, but did not use the mechanism of Okamoto's.
It is something like Jing's Pyraminx.
Here are the photos and video.
Wish you like it.

Another Chinese puzzle designer! Great Job!

Thank you for the image with the ruler.
Do you want to sticker it?

Is this printed at shapeways?
Just wondering .
