Paper mask clip

This is a clip I created to use paper as face mask. I work in a dusty environnement so I need to often change my mask This is a first release, I give you STL and X_T files for the ones whose want to improve it. Fighting the virus is a matter of everybody.

I printed them in ABS with 70% density, Please send me your opinion if you like or even if it doesn't work for you.

Stay safe
