Original lid to wife's favorite Juice Jug cracked. I just happened to have a fresh role of Jessie Elixer, a PLA and TPU blend. Firm, yet flexible enough at 2mm thick to be a perfect snap fit. There is a slight inner lip, just enough to give a pleasant snap fit. Sharing the simple FreeCad file as well in case you want a different size. Cat included for scale.
