Do you desire a natural looking hole instead of a perfectly round one. or do you not have a drill?
If the former, you could drill a smaller hole than you want and nip away at the edges wth some wire cutters or pliers. I like that natural-look idea. I would have just drilled a hole with a spade bit.
If the later, I think you could drill a hole with a knife or the auger on your swiss army knife, then nip away at the edges.
One other thought; You may want to put a small hole on the other side of the 'nut to allow water to flow through. I have no experience, but I have seen folks online worried about anaerobic conditions in a single-opening cave.
