What software you use to create something to 3d print will depend on what it is you want to make. There are two types of 3d modeling software, solid modeling and surface modeling. Solid modeling or CAD is used in engineering, when you need accuracy in measurements. Surface modeling is used in video games, for artistic models. In the world of surface modeling blender from what I found is the best FOSS option. I have not been able to find a good equivalent for CAD... You either have to shell out thousands of dollars or you can find some open source solutions but lack the features. If you have the money, I recommend Solid Works for cad. If anyone knows of some good affordable or FOSS CAD software I'm still looking for my own projects.
