Automa Automatic shutdown module designed for 3d printer

Hello, I am sorry that my English is not very well.(my native language is Chinese) The following statement uses Google Translate. This is the automatic shutdown module I designed a month ago. I use ABS material to print it and it works great. These parts are easy to buy in China and may not be available in your city, but I am still happy to share the structure of my design. There are five parts in total that require 3D printing. The spring of the switch can be used from the common water-based pen. Found, as you can see, using yellow polyimide film insulation in some places, especially on the back of the relay, because the back plate buried in the knurled nut is a through hole that is very close to the high voltage circuit of the relay...I hope you make it smoothly. 你好， 很抱歉我英文不太好,我的母语是中文， 以下陈述使用Google翻译， 这是我一个月前设计的自动关机模块，我使用ABS材料3d打印它， 它工作得很棒。这些零件很容易购买在中国，可能在你们的城市不好买到， 但是我还是乐于分享我的设计的结构，总共有五个零件需要3D打印， 开关的弹簧可以从常见的按动水性笔上找到，如你所见， 在某些地方使用黄色的聚酰亚胺薄膜绝缘，尤其是继电器背面， 因为埋入滚花螺母的背板是通孔，与继电器高压电路距离很近... 希望你制作顺利
