Tevo Tornado - Print Strength and Curling Help

[Solaras]

Hey All -

I'm attempting to print out a spherical honeycomb structure and I believe the diagonals of each hexagon are curling, causing the nozzle to bump into and break off cooled pieces.

I tried increasing the wall layers to 3 and infill to 30%, which helped a bit, but the problem is still occurring.

It almost looks like the nozzle is slightly too close and too hot, but so far fiddling with the settings has gotten me nowhere. Zhop didnt do much either unfortunately.

Does anyone have any experience with more delicate prints like this one?
