I just finished printing this and mine has a physical gap.
I used Cura with stock Ender 3 settings other than 0.16 layer height and print speed of 50.
It's generally a pretty decent print other than the gap, its actually only attached on the top layer. In Cura layer viewer it doesn't look like there should be as big of a gap as I have (it looks like the two pieces should be beside each other) but it is consistent gap the whole way up.
I'm not 100% sure if I printed it in the correct orientation, but I checked the comments and did it the same as someone who asked was it correct (front of the cooling part was on the base of the printer) Supports pulled away clean too.I'm a pretty novice printer and I only got the ender this week so still finding my way around it.
