Hi Christos Did you try fixing the ePTFE membranes to the inside of the sound hole and the 500-mesh on the outside, and did that work well? Sylfest

I need just one acoustic membrane sticker for my single Audiomoth box. Would anyone have one they'd be willing to sell me for a tidy but limited unit profit? Thanks, Sylfest P.S. Failing that, is waterproof audio membrane used in any cheap audio devices one might cannibalize?
