Scaling a mesh without frame distortion

Hey guys,
I am looking for a similar solution to the on mentioned here: Resize object without distortion . Can anyone help me with this?

Here is my stackoverflow question: https://stackoverflow.com/questions/58101657/how-can-i-scale-meshes-so-that-outside-parts-dont-morph-using-morph-targets

Any help would be much appreciated.

Anyone? I’m still stuck with this.
