Lace Mask design perfect for carnival.

It has been designed to be printed in flexible filament, so it is more confortable to wear it. 

Didn't tried it with PLA, but maybe a 1 or 2 layer print would maintain the flexible properties, even though it's PLA.

You can add some strings around the holes on the sides.

Material: Flexible Filament

Layer Thickness: 0.4mm (if you make it thicker the mask will be more rigid)

Tip: This type of designs i make them with Illustrator or Inkscape as vectors and then import the svg. file direct to PrusaSlicer and set the thickness. You can do this with any svg.
I attach the stl. and the svg. file, but I recommend trying the svg. technique.
