Threaded water jug to fitted water jug attachment

thingiverse

I recently installed a water pump for my uncle's refrigerator that uses 5 Gallon water jugs as its source of water. The specific model is this: Flojet BW5000-000A Bottled Water System. before installing my uncle had bought 5gallon water jugs that rate threaded but we came to find out that the thought attached to the water jug didn't make a snug fit. So, I went ahead and design an attachment that would make a tight seal around the threads.
