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.
