突发奇想做了这套幸运麻将钥匙扣，包括“一路大发”“一举高中”“一本万利”“一统天下”“一鸣惊人”五个美好祝愿。

模型使用了分层打印的方式，节约耗材，也可以没有AMS打印（通过暂停手动换料）。目前设置是5种颜色，如果只有一台AMS也可以将某两种颜色合为一种。

I suddenly had an idea to make this set of lucky mahjong keychains, including five good wishes: "all the way to great fortune", "Winning the championship", "a sprat to catch a whale", "Unify the World", and "A blockbuster".

The model uses a layered printing method to save filaments, and can also be printed without AMS (by pausing and manually changing materials). The current setting is 5 colors. If there is only one AMS, two colors can be combined into one.
