I made one of these and just haven’t gotten around to posting the build and the files. I’d is a full sheet of proofgrade cherry and I want it to be the bottom of a serving tray. Need to get the sides glued in to complete the box (hardwood not laser processed) and then pour epoxy over it. I have shapes and names for standard sizes.
I did my ring gauge chart with a spreadsheet. Since they go in 1/64ths of an inch, I got that figured out and then did a kerf compensation so that when I cut the holes, they were within a thousandth. It was tedious, but with the spreadsheet generating the numbers and labels a lot easier.
