Since the tip is going to be something like 0.4mm above the previous layer, I don't see that the lateral distance from the vertical will have a large effect on your prints.

I haven't use trigonometry since I did some bathroom renovations for Archimedes, but I think what you are looking at is called a Cosine Error.

To calculate how far off perpendicular things are, the calculation is: Cos(degrees off vertical) x layer height, which in your case is Cos 5 x 0.4

I stand to be corrected.
