This is a Hummingbird Feeder as the title says. Holds about 400 grams of 4 to 1 sugar water mixture if you use the recommended container (Girard's salad dressing bottle https://girardssaladdressing.com/).
Look online for details on the proper way to make the sugar water: Never use dies in your mixture. Use fresh filtered water and always boil it first to removed any chlorination or microbes before adding sugar. Measure water and sugar by weight is most accurate, 320 grams water to 80 grams sugar will top off the Girard's bottle.
Best to print with ASA to withstand outdoor use.
