Looking at this dovetailed box in the photo, I can’t help but think you could achieve the same look by using a 45 degree spline jig and a dovetail bit on a router table, and slip in contrasting wood dovetailed to fit the slots. If the box sides are thick enough this might not cut into the inside of the box, and the illusion would be intact. If not, could look interesting anyway. Only problem for us Shapeoko converts is how to hold the box at the necessary angle to cut the slots using CC and CM. My router table is but a storage surface these days.
