In summer it is nice to refresh yourself with a cool drink. But on the glass jugs purchased, an iron lid was used. And it was poorly lacquered so it soon rusted. That's why I created a new lid for a beverage mug. It has a better thread and therefore holds well on the mug. And it also grips better for screwing.
Good print result is from the PLA Prusament.Slicer properties: 2 perimeters, layer height 0,2mm, min. 15% infill, 3 top/bottom layers, no supports needed.
