This is an updated version of my last model that you can find here:
https://www.printables.com/model/843324-jug-lid
The main difference is this model is has only one part, I designed with a “negative” handle.
No need to print additional parts and glue them together
I think it's easier to print and more safe without using glue.
The inner diameter of the glass jug is 78 mm. I printed at 100% but it was too tight, so I printed a second one at 97%, now it works fine. The parts must be glued together. Use 2 small pins to fit the two parts perfectly. I recommend PETG. Print upside down with some support at the handle
Attention!
some opinions suggest that FDM printing is not always food-safe, as bacteria can easily settle in the tiny gaps between the layer lines, and they are very difficult to remove. Before printing, please make sure to check whether the material or technology you are using is safe.
