I needed some narrow lockers for a project. Tried sculpting them, it didn't go well lol so thought if I make the fronts in brass for the details and then glue them to cardboard for the depth. Hunted for a company that made lockers and copied the dimensions, that worked
These are various sizes scaled for 28mm scale as they are full height and there are also sculpted ones coming with the same details but in blocks for mass placement.
Etched brass fret is approximately 48mm x 65mm and 0.15mm thick.
