A pipe. I wouldn't recommend trying to smoke it.Model copyright 2012 Chris Webber, commissioned by Rob Myers.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.
