Earbud mesh replacement

I lost the metalpart covering the speaker on my left earbud when I was cleaning it, so I created a new one. Personally I haven't noticed any reduction in sound quality, I am however not super picky about such things. I think it's better to have a cover than not because I believe it's purpose is to hold a mesh behind it in place to stop water from entering the electronics. It fits my Galaxy Buds SM-R170, don't know if it will work for newer buds though.
