This replaces the original bamboo lid, which gets mouldy easily when condensation builds up on its inside. The vent holes allow steam to escape but without letting any dust in.
This lid should be printed upside down without any support. It doesn't require too much infill. Just use your best judgment with the settings.
V2: I moved vent holes closer to the center for better condensation reduction
