Oh, you're right, it doesn't have an actual hole, my bad. I must have just seen it in a photo or maybe it was just painted that way.
Well, I don't know exactly what I'm going for, I just wanted it to be, as you put it "fully see through", it's just that if I took a drill and started drilling I would most probably end up destroying the model (which is definitely not something I want ;-) ).
