Bath tube plug

Bath tube plug.

Duck is from here http://www.thingiverse.com/thing:23372 (I think).

I successfully printed this on my printrbot play using various settings in cura including:
* layer height: 0.2 or 0.1 mm both work fine
* With or without support (without support you will get worse quality of course)
* Speeds from 40 to 80 mm/s
* Fill density from 10% to 100%
