一把来自古代先人智慧的锁头，钥匙的插入方式，弹片锁止机构，无不表现着在古人的智慧，代表着古人朴实的机巧装置。

如果喜欢，你也可以锁一些自己的小秘密：）

为方便打印，锁心部分被拆成了锁头，上下弹片，锁柱三部分，因打印材料不同可能出现过紧或过松的情况。

• 过松可用胶水。
• 过紧用橡胶锤之类的东西砸到底即可，我测试过，强度没问题，不用怕砸坏。

锁壳部分使用了粗壮树，可以有效避免内部支撑倒塌，导致打印失败的问题，但坏处就是支撑会非常难拆，使用螺丝刀+尖嘴钳可以拆除，如果嫌麻烦，可以更改为默认树状支撑，同时修改较慢的打印速度，以防支撑倒塌。

最后，祝玩得开心！

A lock born of ancient ingenuity—its key-entry and spring-latch mechanism speak of the plain yet brilliant devices our forebears crafted.

If you like, you can use it to seal away a few little secrets of your own :)

For easy printing, the core is split into three parts: the lock head, upper/lower spring plates, and the plug.
Depending on your filament, the fit may be too tight or too loose.

• Too loose? A drop of glue will do.
• Too tight? Tap it home with a rubber mallet; I’ve tested it—strong enough, so don’t worry about breaking it.

The housing is printed with “tree” supports set to “thick.” This prevents internal supports from collapsing and ruining the print, but it does make removal a chore. A screwdriver and needle-nose pliers will get them out.
If you’d rather skip the fight, switch to default tree supports and slow the print speed a bit to keep the supports from falling over.

Lastly—have fun!
