... by the way: a front door (like the one in the Advanced 3D Printing Kit from Ultimaker) is highly recommended for successful printing with ABS.
I have read a lot about how to print with ABS, and none of the tips solved my problem... I have changed the temperature, on the extruder and the plate, and it did not solved it yet. I always lower the print speed so that the pieces come out better. My printer also has a door.
However, there is always a layer that comes out with a flaw, and it is coincident with the end of the hexagonal indentation of the metal nut (not the beginning, it is always the layer that has a higher Z coord). This time, the piece came out like the ones in the images in this comment.

To problem 2: I use the Ultimaker Adhesion Sheets on the glassbed of my UM3 and have nearly no problems with warping (but sometimes with week layer-to-layer strength, while i use the Ultimaker / Cura approved default settings). And they can be used SEVERAL times till they need to be changed.

What if you print this in PLA? Does it come out right, or does it also have the same visual defect at the same height (although it might not break due to better bonding)?
And what if you print this on its side? Does it then have a defect at the same height above the build plate (which could indicate a problem with the Z-axis), or does it have the same defect now running vertically (indicating a model defect)?
When moved manually, does the build-plate or Z-axis move smoothly up and down, without hard, stuck points?
Is the bottom of this model open, so you can insert the nut from the bottom? Or did you pause the print halfway, move the head away, insert the nut, and then continued printing? If so, I could imagine this has some influence.
Do all print-settings (perimeter, infill) have the same speed, temp and other settings?
...Justy trying to narrow-down the cause...
