I made this one for salting eggs (i.e. i need a small area of holes on top of shaker)
So when my cat destroyed my ceramic salt shaker i cant find the perfect one in stores and end up in making my own 8)

From http://www.thingiverse.com/thing:30321 i took a screw-thread part.

For base part you don't need support, and for cap part please use support for better results. Slic3r generate nice small supports which is very easy to remove afterwards.
