I like the idea. I have the same “thing” for making coffee but I don’t know the english word for it . Mine is too old and rusty to look so good and shiny.
I thing the modeling is good and the chrome material.
The plastics aren’t real enought, and I don’t like the place where the top connects the bottom part.
After all I like the “thing” and find it very amusing . 
In my opinion I don’t really like that usually people make these kind of objects so clean. I have a couple of suggestions.
Even if it would be this clean it needs some sort of scratches on the metal. And like BorDy said about his. Make it a litte bit used. Makes it alot more interesting to look at. More for the eyes.
Exept for that I really like it.
