E.MONSTER新型肺炎病毒对抗装备 updata： 2020.2.12 因为公布这个文件，我被污蔑为破坏港台关系的人。。。。过程公布在https://m.weibo.cn/6345384823/4471261311084355，可以的话帮我转发。 我不再做这种设计了。 2020.2.11 本着公益出发，却依旧被人盗用打赏，圈钱打赏，这完全不是我本意，绝对不要向任何人支付任何这个设计图或其他索求的费用！ In the spirit of public welfare, but still by the misappropriation of reward, ring money to reward, this is not my intention, absolutely do not pay anyone this design or other request costs! updata： 2020.2.9更新MK3： 为6200这种多气阀口的新增气密伐零件，可以再减少一半消耗量。 本体周围新增一圈护墙，对飞沫防护性能加强。 适用于3m防毒面罩6502Q，6200这类通用接口（其他3M型号未测试），前端是侧面进气，防止病毒飞沫传染，正面可喷洒酒精消毒。 安装方法：将口罩剪成对应的圆形，填入里面前端和圆形垫片之间（口罩如文件中图片蓝色部分），圆形夹片夹好后，后端旋入。 一个口罩大概可以剪9~10次，滤片在吐气不会被口腔湿度传染，相对比之间用口罩寿命略长，一个口罩完全利用大约能使用一个月。但还是推荐定时更换。 打印参数推荐使用0.1层高（越小越好），40%左右填充（越大越好）。 本图纸为公开公益图纸，不得直接或者修改作为商业目的使用。 这个距离是刚好4个模型独立顺序打印（既是完全打印完一个移动到新坐标开始打印，无需人手介入），不会撞喷头的距离。 打印因为有螺纹，也比较推荐顺序打印，精度会比较高。扣合系数已经调整好可以直接打印。 It is suitable for common interfaces such as 3m gas mask 6502Q and 6200 (other 3m models have not been tested). The front end is a side inlet to prevent the spread of virus droplets, and the front side can be sprayed with alcohol for disinfection. Installation method: cut the mask into a corresponding circle and fill it between the inside front end and the circular gasket (such as the blue part of the picture in the file). After the circular clip is clamped, the back end is screwed in. A mask can be cut about 9~10 times, the filter in the breath will not be infected by the oral humidity, relatively longer than between the life of a mask, a mask can be fully used for about a month. But regular replacement is recommended. It is recommended to use 0.1 story height for the print parameters (the smaller the better) and about 40% fill (the bigger the better).
