Pretty good. I'd be happy with that. But there are a few things you can improve. The thing that bothers me the most about this print is those horizontal lines.
That could be temperature fluctuations but if so it should be obvious by watching the temp while it prints it would have to fluctuate 10C. More likely it is the Z axis.
What kind of printer is this? Does it have one z screw? two? If the printer is less than a month old then you probably have a crappy z screw, or z nut, or bearings. If it's older than a month then hopefully the z screw is just dirty and needs cleaning.
What is happening is that Z movement is inconsistent. You sliced for .15mm layer height but the Z is moving too far sometimes and other times not far enough. On times when it doesn't move far enough you get overextrusion because there isn't enough room to put all that filament in a layer that is say .05mm thick but enough filament for .15mm thick. So you get a layer that sticks out. When the Z moves too far you get underextrusion but it doesn't look as bad. It's still there though.
If this is a new printer and it's not an ultimaker you might need to replace some or all of linear bearings, z screw, z nut to some higher quality parts. These are not expensive parts.
Another Cura release has arrived and in this 5.8 beta release, the focus is on improving Z seams, as well as completing support for the full Method series of printers by introducing a profile for the UltiMaker Method.
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
