The file 'Home Brew Beer Wort Aerator 3D Printer Model' is (stl) file type, size is 108.2KB.
I originally downloaded and adapted the one made by lb but it wouldn't fit my smaller hoses. So I did a small modification that allows it to fit my 3/8" I.D. hoses!
Edit: Originally I had uploaded the wrong .stl file. Fixed now!
