(named by GF)
designed for Project “Cocktail mixer”:
Since I´m still working on a project I designed the Model to
1)be easily fixed on a surface with two screws and
2) to unplug the tube easily, without screwing the Model apart and unplug something the tube is connected to.
There might be a drop come out after the tube gets pinched down but in total it works pretty good.
