Precision work, very impressive. Digging the typeface.

I cut also the ring with the laser, it took me around 10 minutes to engrave the number + cutting. It's 0.4 mm the thickness :)

@bumby26 That looks really nice. Did you use the laser to also cut the ring out, or was it already cut before engraving? If you cut it, how thick is the metal, and long did it take?

I'm asking because I have a 50 Watt fiber laser arriving Soon™.
