When slicing for a filament printer, set the position in the verical axis negative by 0.5mm, so that the model intersects with the baseplate, that way the slicer will give the model a flat bottom (it will basically cut off a small bit from the bottom).
This will make printing much easier and you do not need supports.

Also recommended: use "inclusive" setting under "Slicing Tolerance", the ears are pretty thin and with other settings it may not properly slice them depending on what scale you're printing at. These settings may be called differently in different programs, I'm using Cura.
