This will hang on the door of my wife’s mother’s apartment.
The “wood sandwich” is birch and walnut. I bought the individual models from the Vectric Design and Make site, then made up my own composition. I used a 1/4" down cut end mill for the roughing pass, a 1/8" ball nose for the finishing pass, and a 1/8" downcut end mill for the cut out. The finish is 6 coats of satin rattle can lacquer.
Overall size if about 9" almost square by 7/8" thick.
