You could start from a default Cube and use modelling tools described above to get at least some results to further be a bit more specific to your Blender related problems and questions.
If there are none while you get the initial rough shape then proceed to what is described here: https://www.blender.org/manual/painting_sculpting/sculpting/index.html#sculpting

Depending on what’s the intended outcome you could apply retopo process and UV unwrap/texturing or check for the mesh errors and export model for 3d print.
