I'm pretty sure this is an issue with your STL file. Did you create this model?
If you did you probably want to reduce the qty of triangles created when you exported to STL. When the triangles get smaller than around .1mm you start to get stuff like this.
If you didn't create this then I would pass this model through meshlab and remesh it with quadratic decimation. It's very easy to do - one menu option possibly cut triangles in half or 1/4 and then click apply. More here:
By the way I'm pretty sure you don't want support for this part - it's more trouble than it's worth. FFF printers can "bridge" just fine. The only overhangs you have are all bridged (supported on at least 2 sides).
