哨兵 Whistle soldier

这是一个口哨，可以吹响。我本来只是想尝试制作一根风琴管，然后我给风琴管加了一个吹嘴，有意思的事情发生了，这不是绿野仙踪里的铁皮人吗，哈哈！于是我决定把它做成一个“哨兵”。      我是用PETG打印的，如果你用PLA打印，发现卡笋容易折断，请尝试打印第二盘的替换件（为PLA重新设计了卡笋结构，需要一小段耗材当作转轴来连接）   This is a whistle that can be blown to produce sound.I originally just wanted to try making an organ pipe, but then I added a mouthpiece to the organ pipe—and something interesting happened: Isn't this the Tin Man from The Wizard of Oz? Haha!So I decided to turn it into a "sentinel." Interestingly, in the Chinese word "哨兵" (shàobīng, meaning sentinel/guard), it actually contains the character "哨" which specifically means "whistle." The picture is printed with PETG, and it can also be printed with PLA. If you print it with PLA and find that the latch (or catch) breaks easily, please try printing the replacement part instead (I redesigned the latch structure specifically for PLA; it requires a short piece of filament to serve as a pivot shaft for connection).
