The drawings have two diameters drawn - the reason was answered in this post when I asked a similar question (before having them made thankfully!) - the larger diameter is for a countersink when using a thicker plate.
The holes you have are probably 7.2mm diameter and they should be 3.2 - in your shoes I would print a couple of small cylinders of those dimensions use enough perimeters so that you have a solid part, and use them as spacers. That’s probably not the optimum solution, but I suspect it will be good enough.
