Thank you very much for your response.
I checked in Cura and the object does not consist of multiple parts. After increasing the infill overlap to 20% print got better, but still weak between the bottom part and the upper part. What is a good recommended value for the infill overlap?

I can see that cura is putting a shell around the outside of the bottom piece. This means Cura thinks these are 2 different pieces.
OpenCAD or openSCAD?
Anyway you need to make this into one piece somehow - delete all the walls that seperate the lower part from the upper part. This is a CAD issue.
Alternatively you could try "fix horrible A" or "fix horrible B" in expert settings - look at it in slice view and make sure Cura is not putting a shell pass (red line) separating the lower portion from the upper portin.
