The 五位数密码锁Five Digits Combination Padlock（Recreated 6-9 Digits）更新6-9位数。 is a free printable 3D model from MakerWorld by 补补觉去. 原设计完美复现了拨轮密码锁的解构，但3位数的密码强度太弱，我重新修改了5位数的密码锁，密码从216个组合升级到7776，大大增加了密码破解难度。模型缩小到70%和80%仍然具有良好的性能，低于50%结构强度不够。安装和原理请参考原设计作者。还设计了6-9位数的密码锁，供娱乐。 The original design is great, I love it. You can download the STL file from the original listing below and print it at home.

About this model

原设计完美复现了拨轮密码锁的解构，但3位数的密码强度太弱，我重新修改了5位数的密码锁，密码从216个组合升级到7776，大大增加了密码破解难度。模型缩小到70%和80%仍然具有良好的性能，低于50%结构强度不够。安装和原理请参考原设计作者。还设计了6-9位数的密码锁，供娱乐。 The original design is great, I love it. But the original design of 3 digits, I think the strength is not enough, I remixed a 5 digit lock.From 216 possible combinations to 7776 possible combinations.70% and 80% still have good performance, less than 50% may not be effective due to insufficient strength of the material.It is recommended not to use PETG when printing at a ratio of 70% or lower, and to use PLA to ensure better rigidity.Please refer to the original design author for installation and principle. At the request of a friend, I recreated 6-9 digits Combination Padlock,further increases the complexity of the password.
