Tired of your 3d-printed holes being a nozzle-width too small?

I am, so I looked up how Curas horizontal hole expansion and how the slicer can compensate for it.

Don't know what horizontal hole expansion is and what it's used for?
Basically it's used to compensate the nozzle dragging material in towards the center of the circle/hole, which leads to the hole being the wrong dimension.
Read more about it over at this link.

Basically if the hole in the model you printed measures 5.5mm instead of 5mm, your horizontal hole expansion is -0.25mm.
