So in sketchup the default material is white on the outside and gray on the "inside" - the side facing solid plastic.
You have this backwards on your holes. So right click on all gray surfaces and choose "reverse faces". Then re-export to STL and you should be fine. I suspect the only problem spot is the inside of those vertical holes.
Much more details here:
