So if your SodaStream bottle was in the dishwasher and maybe it was a little too hot, it probably lost the original base because the glue got washed off. Maybe that's why I made a new base and kept the bottle the way it is, so it can keep going into the dishwasher. It's a lose part and the bottle just sits atop. Or if you want to take it with you, you can clip it on the cap.
