Sorry, I wrote this before leaving to work. I'll upload it when I get home today. This is the gcode right?
I guess that your model has not enough cooling. Print this slow, as cool as possible, and print a dummy model next to the real model. Try a dummy cube, or an inverse of the model. So that the hot nozzle has to spend some time away from the real model, and the real model gets time to cool. But as said, it is a guess.
See this conceptual example:
Edit: it looks like this effect with and without dummy cooling tower:

With just a picture, we cannot help. So you have to give us more details or even better, upload the Cura project here.
