Mask for Covid, deconstructed from 3D model
I print tested this so that you don't have to!
Mask and strap:
NinjaTek 3DNF01129010 NinjaTek NinjaFlex TPU Filament
0.3 mm nozzle produces best results.
adaptive layers required for best mask results.
Material for other parts are your choice, but I used PLA.
CURA 3.6.20 Lulzbot edition used for slicing. Might be usable on other slicers.
Note: Mask and filter holder were modified, but the 3mf and gcode were not. You should re-slice on your own slicer
