A pipe. I wouldn't recommend trying to smoke it.

You'll need to center this, and it definitely needs a raft and external support (although not internal support).
I recommend adding two extra shells in Skeinforge. This is to avoid gaps in the skin of the stem, given its slope.
You may get better results rotating it around the Y axis so it's sitting on its base rather than its side.
