That would get tid of the overhang. Some parts are just problem parts and sometimes need creativity to print them.

Even if layer time is set to 25 seconds I have not had much luck myself with that working all the time.

For an object that size I would be printing at closer to 20 or 30mm/s. I also would make a layer fan that fit on my extruder so that the cool air could hit the layer directly and more concentrated.

I already saw this topic in another post, but i can't get an answer. So my problem is that  overhangs it tends to curl up.
Print
ABS-plastic

speed 40mm/s sometimes 60 mm/s
Temp 230º sometimes 250º
Bed temp 100º

I change my extrusion from 95 to 80 and i got the same results,
minimun layer time 25s

i ran out of ideas about it, I even tried a fan blowing direct to the extruder and i get the same results
Hope osme can help me, thanks

I upload some photos of the problem
