Ozark 30oz tumbler lid cover

This is to cover the large slot in the Ozark 30oz. tumbler lid while allowing the use of a straw. This is to keep out bees and gnats. I use a Starbucks straw in mine, it deforms to fit the elliptical opening in the cover. The cover fits snug, just press it in from the front of the lid with your thumbs. To remove it, press it out from the back of the lid with your thumbs. 2 versions, 1 with holes and 1 with no holes. The holes serve no purpose other than to save a little filament and print
