I'm a Bioengineer with studies on Embedded Systems at the FIUNER (Facultad de Ingeniería de la Universidad Nacional de Entre Ríos). My favourite tool for designing is SolidWorks, but I also use MATLAB, and Blender.
If you want me to design a particular case for a phone, I'll ask you just to test the prototypes for it.
