Does it need any support structure?

The quick answer: YES.
But attach the STL file and we might be able to give a better answer.

That's the kind of object where it is probably worth designing support into the stl, then printing without support enabled in the slicer. You can probably get away with a couple of thin walls, and let the rest be bridged. For example, I designed in support on this: [www.thingiverse.com] which significantly reduced the amount of support material, and increased the quality of support compared to slic3rs default.
