it's abs.
basically it shrinks, which creates the cracks.
2 things to try. print slower and lower resolution 0.3 rather than 0.2 and try less infill. The infill also shrinks which pulls the sides in and cracks the layers.
So 40mms print speed and between 5 & 10 % infill. Hollow with 3 shells if you can get away with it.
Less infill should counteract a slower print speed so the overall print time should be the same.
Also a lower print temp - say 225 or 220, will help if the filament will print at it.

Used to get it a lot with abs. never had it with pla.
I guess the acetone smoothing is your objection to pla ?
fair enough :-)
