由于我有时候打印的一些模型有螺丝螺母，但是由于各种原因导致模型收缩，螺纹对不上，所以我自己设计了一个可以用来辅助攻丝的小扳手，简单好用，适用M3~M10的丝攻。

由于需要受力，打印配置的强度偏高，可以根据自己的使用场景调节。

谢谢支持。

Since some of the models I sometimes print have screws and nuts, but due to various reasons, the models shrink and the threads do not match, I designed a small wrench that can be used to assist tapping, which is simple and easy to use, and is suitable for M3~M10 tapping. Due to the need for force, the intensity of the print configuration is on the high side, which can be adjusted according to your own usage scenario. Thank you for your support.
