Delonghi steam handle

This is the lever used for hot water in the Delonghi Magnifica S coffee machine. I have made this because the original one was broken. The spines were very difficult to draw because they are very small compared to the 3D printer capability. That is the reason why I had to make several protos (just small rings) to have the best fitting.
It has been made in ABS.
As the model 1 was not tight enough, I propose also the mdel 2 as probably better part but this model 2 has not been printed. The model 1 fits well with addition of a little glued paper tape inside the groove.
