Think about the assembly process when you're designing robots, that helps me the most. You can usually just pound them through with a gentle persuasion tool if the hole is a tad small.

I intend to weld the cross beams to the inner plates. Our team has a CNC mill, but it doesn't have a coolant system built in, thus milling operations can be quite cumbersome. By designing it this way, the only CNC operation necessary is the drilling of the holes so everything lines up square. The rest of the dimensions are more or less non-critical and can be cut with some careful band sawing.
