Conical lid for wine decanter. Print with a quite high density and not too small : it must not be too light to stick to the carafe. And please, please, do not print it with the any plastic you get your hands on. You will first kill your wine and second kill yourself. I use Taulman 3D PETT (FDA approved). If you insist on using PLA, at least use "natural" PLA, and avoid touching the wine with it : PLA itself is quite safe, but it is also a good nest for very unsafe dirt and bacteria.
