Mug Cover/Cup Lid Practical Cup Lid

The original cup lid was broken, so I designed a replacement with dimensions: "outer diameter 92mm, inner diameter 68mm, height 15mm, thickness 2mm". Note that it is only suitable for cups with an inner diameter exceeding 68mm and an outer diameter less than 88mm (most mugs fall within this range). The default setting is horizontal printing.

I have experimented with vertical printing, and the results are excellent. I recommend you try this method as well; it mitigates the issue of unsightly layer lines on the top and bottom surfaces.

Select 100% infill and leave no internal voids. Otherwise, thermal expansion and contraction from hot or cold liquids may cause damage.
