Thanks for the detailed reply [USER=2002]Peregrinus[/USER]!
I ended up tweaking my model a little and ended up with this:
[ATTACH=full]215474[/ATTACH]
It's on a 3/8 wood dowel from Home Depot. I chose that diameter based on what I measured on [USER=597]stormtrooperguy[/USER]'s ROTJ whipcord model, scaled to 103% (I actually used the whipcord from here since it has a hole for the hose connector).
If I were to print it again, I think I would use a raft for the bottom piece.
Overall, I'm quite happy with it!
