适合 3M 6000, 6500, 6800和7500系列的面具.
特性：高度还原3M面罩的卡口设计、方向性设计、对称设计、防喷溅设计、方便安装和FDM打印等等
本模型可以作为传声模块使用，也可以作为应急滤盒使用：
1.传声模块模式：使用厚度0.1mm-0.3mm、直径50mm的圆形振膜，目前公测振膜材料，可以尝试PET、PU、丁基橡胶、金属等；硬质材料请添加0.5mm-1mm厚的密封垫圈来保证气密性；传声模块模式下可以把进气阀门取下来以获得更好的效果。
2.滤盒模式：使用直径50mm圆形滤纸放入其中压紧即可。你可以做负压气密性检查，用手掌盖住开口后轻轻吸气。最后再盖上防护罩。
▲警告▲
本模型没有经过任何专业机构的测试和认证。
虽然我打的模型有良好的气密性，但每个人的情况可能不一样，你要对自己的情况负责。
记得每次戴上面罩前都要进行气密性检查。
Original model by Yond, no charge | CC BY-NC-ND
Designed for 3M 6000, 6500, 6800 and 7500 series respirato.
Features：Finely built bayonet structure from 3M reusable respirator, direction design, symmetrical design, anti-splash design, easy assembly, friendly with FDM printe.
This model can be used as a voice module or as an emergency filter adapter↓
Mode 1→Voice Moduleound tramission module
Cut a circular diaphragm with a thickness of 0.1mm-0.3mm and a diameter of 50mm, use a seal gasket (0.5mm-1mm thick) if you choose a hard material as a diaphragm. Currently, the diaphragm material is under public testing. Peonally, I tested 0.3mm PET and 0.1mm PU, both are not so ideal, so you can try things like rubber film, thinner plastic film, etc. You can remove the inhale valve to get better performance.
Mode 2→Filter Adapter mode
Put iide a piece of circular filter material with the diameter of 50mm and finish the itallment. You can perform a negative pressure user seal check by covering the opening using palm of your hand and then inhale gently. Put on the protection cover afterwards.
△CAUTION△
△This design is NOT tested and certified by any professional authorities.
△Even though I tested very good air tight sealing, it can be different in your situation when it comes to print and itall, you are respoible for your own case.
△Remember to do a user seal check every time you put on your respirator.
