Just did a test engraving on my Gravity Chopsticks! My Nomad is pretty accurate. First try turned out pretty good. Going to have to run 100+ pieces for my Kickstarter rewards.
I used a 90 degree V-Bit from precisebits http://www.precisebits.com/products/carbidebits/scoreengrave.asp
I have a delrin tray milled out to squeeze the chopstick handle into. I still need to figure out a good way to pull it out of the tray without damaging the aluminum part.
I imported my logo (svg) into Carbide Create and ran the contour path. For the text I used Carbide Create text tool right out of the box. Also with contour path.
Will run a few test parts through nickel plating finish and see how it turns out.
