It was about 4" tall and I used .25 as the layer height. I flexed it just a bit to test it and it split between layers. So I reprinted it a .18 and when I tested it, it was really tight. I even bent it pretty firmly and it did not separate.

I'm not sure if my printer was malfunctioning or it it's just the nature of layer heights in general, but from my experience, I don't trust the integrity of prints with thicker layers as much as I do those with thinner ones.
Same experience here, my sturdier prints are all 0.1mm or lower. I do think parameter (shell thickness) plays a bigger role though.
