If you mean those tiny little “cracks” in the orange filament in the middle/top/center area, I suspect those are artifacts of the graphics card/driver in your PC and not something that’ll be reproduced in the print. If the slicer was starting or stopping at those points, there’d be a white “seam” dot there. And if there’s no seam, then there can’t be any gaps. Even if the extruder stopped extruding for that short distance it wouldn’t matter. It’s just too small.
Print it and see what happens. Slice the bottom off so you only print the region with the defects of concern so you don’t waste a lot of filament if I’m wrong.
