Ikea lack table enclosure coupler 16mm riser

All of the designs I found for a lack table coupler were in metric, and metric glass dimensions and since I am in the US metric sizing is hard to come by. With these couplers, I designed in tinker cad your glass size is 32in X 17.5in on 3 sides and the doors I am going to use 32in X 8.5in (2).
