Summary

I got a neck tube to keep my face warm when running in the cold, but it's too thick to breathe through and fogs my glasses, so I printed this breathing hole. It covers everything except the nose and mouth, so let's call it an antimask.

Note that this doesn't keep the lungs warm, so its practicality is debatable.

To assemble, cut a Y-shaped notch in the fabric, fold 3 flaps over the base, and press-fit the two halves together. I printed in PLA with tree supports under the nose arch.

You can adjust the sizing in Fusion 360; nose_height and fabric_thick are probably the most useful parameters. I bent some copper wire to roughly fit my face, then measured it with a ruler.
