Cave Nests

Good Evening,

I just tried printing my first set of Cave Nests. I noticed when they were done that there was some weird cracks left in the eggs that I don't see when I look at them in your pictures of printed terrain. I was wondering if there was a certain way I should be printing them on my FDM printer. I have an Ender 3 Max and am using the Cura 4.10 settings.

Any suggestions would be helpfull.

Thanks
