customizable air pump nozzle

This is a nozzle to connect an air pump to air mattresses, floating tires and stuff like that.
It's highly customizable and the default values produce nozzles with different tip-diameters for standard car-tire pumps.
This generates several nozzles, you can change the number.
read the comments in customizer well.
This can be generated with or without support. There are different parameters for the support, like thickness and vertical and horizontal object-distances.

I haven't printed this myself yet. So I'm especially happy about successful makes of it!
