Printing as-is may be a snug fit. To ensure it fit I printed with the following:

Horizontal Expansion= -.4
Initial Layer Horizontal Expansion = -.4
Hole Horizontal Expansion = 0.0

Note: If using the 2-piece cabinet sides you will likely want to stretch the print a little to account for the edge pucker where the pieces join together. To do this in Cura I unchecked "Uniform Scaling" and then added .8mm to the Y-Axis before slicing. This fit perfect for me.
