Round holes

Hi, I am trying to print a cyclone. I am using curaengine, 245 extruder, 110 heatbed and abs. Here is the cyclone:

However the vent hole is not round, I have one more shot I think to print it right. Here’s an up-close of the hole:

Using the conditions mentioned; curaengine, abs, repetier, how would I go about this?

I think you will need to print it with support material to keep the “vent hole” from sagging.

Cool, I’ll do it.
