Hummingbird Feeder Ant Moat with Solidworks 2014 Source.

The ants were so bad this year that I had to do something. I went out to see why my hummingbirds had been mia for 2 days when I had just cleaned, and refilled, the feeder only to see a dead ant floating inside the feeder. I looked closer and there was an ant trail going to it. When I grabbed it and flipped it over about 30 dead ants went floating to the top with another 20, or so, dead ones trapped in the inner part.
So, I grabbed a 13 gauge wire hanger and printed this. The hole is 2.1mm so made for a 13 gauge wire coat hanger but you could use anything you wish just be sure it will not rust.
Hummingbird_Feeder_Ant_Moat-2.sldprt is with the center being hollow. The stl is of Hummingbird_Feeder_Ant_Moat.sldprt
I have added a size reduced model, with source, that will print much much faster.
