This is a remix of the awesoe 1X Kong Holder by bobby. I enlarged the original holder slightly as I found it difficult to insert and especially to remove the Kong. More importantly, there is a plug at the bottom that seals the small hole through which my Yogurt keeps leaking.
For those interested in replicating, the plug is 7 mm in diameter and 3 mm tall (starting from the surface of the base plate).

Slightly enlarged the model for easy Kong removal and added a plug at the bottom for better sealing. See description for details.
