I build this project because I just can't buy myself a mask to avoid COVID-19. So I try to make one on my own. The filter of the mask can easily be changed.

You need to print the Mould first then assemble it with "Mould_template" which need to cut by laser. Then use a vacuum machine to shape the EVA foam. Cut the whole from the mark.

The Intake and the Exhaust part will need several M2x6 dish head screw. the Valve part of the Exhaust is made by laser cut 1mm EVA. That would make sure all the air come in from the Intake part.

I'm still working on it and making documents. Apologize for can't having a complete assemble guide. I'll make it done ASAP.

If you got any question, please feel free to ask.
