Hello Rob,
FreeCAD is nice for modeling 3D shapes.
For 3D printing, depending on the technology of 3D printer, you need to process original
model to convert compact sections into hollow honeycomb structure, and add small plastic
bars into empty volumes to support the model while it's printed.
I'm not expert of this latter procedure and tools.
Cura does a great job of slicing the .stl model and
computing the infill, support, etc.
