Ikea Lack Enclosure - Modified top corners for 6mm / #14 Screws

The guide I was using recommended 6mm * 25mm screws for attaching these parts to the underside of the top table for the enclosure. I found that the #12 screws I used did not thread into the preexisting holes in the table - the screw is too narrow. The original dowels that come with the lack are 6.6mm in diameter so I had to use a #14 screw (6.5mm) in order to utilize the holes in the underside of the table. This remix takes the original top corner pieces and makes the screw hole deeper and more chambered to fit the #14 screw flush, so that it does not interfere with the mating lack leg.
