Covid Mask Fix for Fogging Glasses

thingiverse

Wearing a mask is super-important for fighting the spread of COVID-19, but facemasks and glasses present a problem as exhaled breath inevitably escapes upwards alongside the nose to fog your glasses! I've been working on a fix for this for a little while, and this seems to work really well. It's a solution that applies to *fitted cloth masks* - I have included the .PDF instructions for making the mask from our local mask-making sewing guild here in the Seattle area, Maskers Against Covid19 (support them if you can!) https://craftersagainstcovid19.org/patterns/ There are two sets of printed parts to make - you need two of the side_vent.stl and one noseclip. Because people have different sized noses, I've made 6 widths and length combinations - printing them all and seeing which one fits is minimal wasted filament. I've also included the SolidWorks files if you want to modify further. Press the pieces on the bridge of your nose where sunglasses would sit, and pick one that seems to fit best and to sort of stick on your nose a little bit. What you do is, as shown in the photos, stitch a small line along the upper bridge of the nose on the mask to form a narrow pocket between the two pieces of fabric. Slip the nose clip into that pocket. Then, on the outer edge where the mask tie goes through, route the curved side vent on the outside of the tie. Do this on both sides. When you have it configured right, the mask will catch particulates from your mouth and nose, but will vent along the sides of your face and back towards your ears instead of upwards towards your eyes. Voila! You can wear glasses with your mask!
