From what I know (because I have not assembled and have not assembled this set yet) the crack is on the "back" side, so it will not be visible.
It's all about tightness because despite the crack, the entire casting is quite stiff
and after mounting, no one will jump on it.
a drop, I do not know if it can do it - because the breakage is caused
the slight elasticity of this wall - that is, after a crack, the wall is slightly tilted.
But due to lack of time and resources, he can use it - a drop in a crack
and then colorless silicone from the inside (or from the outside too).
However, if someone else does something else, let me write.
