I added a smaller version. I thickened the walls a bit so it can be reduced by up to 50%. In the print profile it is currently reduced to 70% of its original size so it can be printed on A1 mini. 

There are two versions of bubble nozzle in the print profile. If you are printing at 70% size, print the one with thin lines. If you want to reduce it even more, print the one with fat lines.
