A common problem with carwashes is that the tip (the Teut) of the vacuum cleaner disappears. After all, the teut can be clicked loose and will remain in a car.
To prevent this, we have designed a teut for a car wash that cannot be separated: it consists of 2 parts that can be rotated together. Once they have been clicked together they can no longer loose. In turn, one part is tightened on the suction tube. Thus the teut hangs on the suction tube and can be perfectly turned around so that the suction tube never gets "in the knot" during use.
Because of the small required numbers (tens), 3d printing is the most suitable production technique.
