Here are a few miniature badges for a Rover P5 1/10th scale model. The badges themselves are 2.4mm high x 19mm long by 0.5mm thick. The letters are just 1.5mm tall and were cut using a 0.1mm diameter cutter.
Even though the physical sizes are small, there are still 8,500 lines of machine code involved in the machining of these.
I have now made a grille badge in brass for the same model. Size is 6mm tall by 4.5mm wide.
