COVID-19 MASK

Hello guys!
I realize, that often wearable mask in which we feel comfortable is as light and small as possible. So, I did my best to improve model for thick filters (0,5 mm - mask / cotton t shirt). I tried to make every entering level for air smaller and smaller to have construction space for not letting in unfiltered air around filters.

Enjoy!

I attach .step file and Fusion 360 file as well, if you need to correct something or make bigger space for your filter. I would be grateful for every like or tip.

I designed it, but as a amateur, I am not sure about porosity of 3D printing or this construction and possible gaps, I recommend to use official products and respirators, but as I read, It is always better to wear someting that nothing.

Stay safe and use proper filters (probably the best is FFP3 - nice article about filters (in spanish):https://docs.google.com/document/d/1qcUulXBupfjPoHO8ndF7U2yxTGApq1IXWNcBXVhNDRU/edit?usp=sharing).
