You might try adding a small fillet or chamfer to the inside corners of the model. 3D printers don't like making sharp, pointed turns; rounded edges (or wider angled turns) tend to print much better.
The rounded (fillet) corners will probably be less visible, and will prevent the start / stopping point where the problem is occurring
Avoid fillets and use chamfers if at all possible. Fillets will often call for printing supports or just look bad. But the common 45 degree chamfer will be easily printed and look better when done.
Chamfers are to be preferred over fillets.
The corner is laying down. The would be no supports in either case, and the fillet avoids hard turns while the chamfer still has two (less sharp) angles.
Like 99% of things in 3D printing, "Xs are to be preferred over Ys" is an entirely circumstantial statement that is never going to be true all of the time.
"Preferred" doesn't mean "all the time". But chamfers are easier to get nicer results with the majority of the time because they are easier for the printer to make.
It depends on the orientation you print in.
ah. I'll try that, thanks.
I would also try to increase the printing temperature a little bit, that can make stuff stick together better.
