Jug lid

UPDATE!!!

I made another vesion: check it out:

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. See pictures for print position, 0.2 mm layer, no support needed, brim only for the pins

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.
