我为了标记我喜欢的书设计了这个印章的初版，它打印的很平直，但是却不像是一个传统的印章，反而像是一个冰冷的机器。我的母亲告诉我传统印章用石头雕刻时总是会有一些小的缺陷，正是这些缺陷才让它变得有趣。

所以我重新设计了OpenSCAD脚本，用来添加一些随机的缺陷，让这个印章看起来更真实。附件中的OpenSCAD脚本可以快速创建一个类似的印章。

I need to mark some great books I have read. So I designed the very first stamp. The frame is printed straight and perfect. But it is cold like a machine, not a traditional Chinese stamp which always has defects on it because the traditional ones are made of stone.

So I rewrite the openSCAD script to add some defects on it and make everything easier to create a traditional-like stamp.
