After learning about the handy "ear savers" people were 3d printing to help folks who had to wear protective masks every day, I decided to help out. I have printed about 500 of these, and given away about 400 so far.
If you know anyone that needs them, let me know.
I found a design that I liked and allowed me to print as many as once as I could on my 3d printer bed. I did modify it to bring down the number of layers I had to print, but keep the structures holding the elastic bands stiff. I have run through about two spools of filament so far.
