I model for my 3D printer in Blender, because that's what I know. I thought I might be missing something not using a parametric modeler, so I tried FreeCAD to reproduce one of my models. It was a struggle, but I got it done. The end product mesh was the same, though. There wasn't really any advantage for me, already knowing blender quite well, to switch to FreeCAD for my work. So, I stuck with Blender.
