It will be awesome, if you added some settings to make holes and walls thicker.
Cura has Horizontal Expansion and Slic3r XY compensation settings, i desperately miss it in Astroprint.
Horizontal expansion can greatly help you if the tolerance of the print is important. Due to the slight deformation of plastics the actual dimensions of the print may not completely correspond with the dimensions of the digital model. By adjusting the horizontal expansion value you can compensate for this slight deviation. A higher value will increase the X/Y size of the model, while a negative value decreases the X/Y size.
Horizontal expansion -1 mm, no horizontal expansion, horizontal expansion +1 mm
