I wonder if the original submitter of the inventory even had ones that had a
square hole. They may have only looked at the part number on them that said 66906
and added that one without actually checking the holes. It would make sense because
the set cannot be built with the square hole version. I think we should remove
the square hole version from the inventory completely.
