注意此设计只适用于胶把的钥匙，目前测过的钥匙只有9种，去掉塑胶后金属钥匙芯和相应的尺寸如下图（注意实际尺寸可能会有些不一样，可以添加修改器微调）。其他钥匙没测试过，如果会建模，可以下载附件的stp源文件修改。Note that this design is only suitable for keys with plastic handles. Currently, there are only 9 types of keys that have been tested. After removing the plastic, the metal key core and corresponding dimensions are shown in the following image (note that the actual dimensions may be slightly different and can be adjusted using modifiers). Other keys have not been tested. If you can model, you can download the attached stp source file for modification.

打印说明 3D printing Instructions：

盘名的规则为（零件名-钥匙芯序号）。选择需要的打印件打印，是哪种钥匙芯，就打印对应钥匙芯序号的所有盘零件。比如需要做钥匙1的，就打印：（外壳 Shell-0 1）、（内壳 Inner shell-0 1）、还有（钥匙固定 Key fixing parts-1 2 3）三个。最好开静音模式（速度50%）进行打印，以达到较好的表面质量。The rule of disk name is (part name - key number). Select the required print for printing, which type of key core, print all the disk parts corresponding to the serial number of the key number.For example, if you need to make Key 1, print: (外壳 shell-0 1), (内壳 Inner shell-0 1), and (钥匙固定Key fixing parts-1 2 3). It is best to print in silent mode (50% speed) to achieve better surface quality.

装配需要准备的东西：4颗杯头自攻螺丝M3*4（自攻螺丝最好，实在没有，用机牙的也不是不行，建议用不锈钢的），需要将钥匙的塑胶部分去除掉，留下金属部分。Assembly needs to prepare things: 4 cup head self-tapping screws M3*4 (self-tapping screws are best, it is recommended to use stainless steel), the plastic part of the key needs to be removed, leaving the metal part.

装配过程Assembly process：

1 . 往钥匙固定件的三个方孔里涂上强力胶水，将三个插销插入方孔里，装上金属钥匙芯；2 . 在三个插销和周围的对接面也涂上强力胶水，装入另一半钥匙固定件，用力压紧，确保没有缝隙，并且保证钥匙芯没装歪；3 . 等待胶水彻底固化后，装粘好的钥匙芯插入内壳里，往中间的孔里拧上2颗杯头自攻螺丝；装上外壳，再拧上2颗螺丝，至此，完成安装。 1. Apply strong glue to the three square holes of the key fixing piece, insert the three pins into the square holes, and install the metal key core; 2. Apply strong glue to the three latches and the surrounding butt surfaces, install the other half of the key fixing parts, press firmly to ensure that there is no gap, and ensure that the key core is not crooked; 3. Wait for the glue to cure thoroughly, insert the glued key core into the inner shell, and screw 2 cup head tapping screws into the middle hole; Install the shell, and screw in 2 screws. At this point, the installation is complete.
