The mouthpiece generator allows to generate the model by modifying traditional parameters .
It is thus possible to make as many combinations of these parameters as possible.
Unlike other CAD tools, the script in OpenSCAD language, can be changed very quickly and some configuration files can be understandable for non-computer scientists like musicians, for example.

The purpose of the generator, if all goals are achieved, will be to make custom mouthpieces while guiding the musician on his choices, between-other with a calculation of the influence of his choice of parameters on the accuracy so it can find a configuration that best suits him.
For old instruments, it will be possible to find a mouthpiece that compensates the defects of accuracy that can cause modern mouthpieces for example.

As explained in the documentation of 3D printers, for now OpenBrass does not recommend the use of all types of technologies / materials for daily use.
However it is possible, after finding good parameters, to produce the model with CNC machine as do the current manufacturers.
