Playing with the Longer Ray5 10 Watt laser engraver and Rotary accessory today. I asked Freebird if I could use the VR logo on my travel cups and he graciously allowed it.
The black cup was a PITA! I ended up masking the engravings off and shooting the cup with a rattle can as the clean up with acetone(alcohol wouldn't cut the shmutz) dulled the original finish horribly.
The SS cup turned out quite nicely.
