Non-uniform scaling

In this previous post,
Scale individual axis without locking the other axis, please
it is indicated that preform would be too complicated to use if this function would be added … (I dream?)

It is also indicated that it is enough to modify the scale in a CAD drawing program … yes if you have done the drawing yourself, but that must print files already in STL format I don’t want to complicate my life with another intermediate program !!!

FYI: with CURA that I use with my ultimaker 3, this scale function has been around for a long time

Thanks
