I am pretty pleased that these were so successful on the first attempt!
I used 200 (speed)/100 (power) on 1 pass. The Evermore Studio ambigram logo was a vector “score” while the spirals were an engrave at 225LPI.
I cut a cardboard jig for holding and positioning, then used the paper marking technique to align it. Here’s a shot of the setup:
Great job on it! (And nice jig work.) 
These are great. Do you have a link to where to buy the flash drives?
Wow, that really came out nice!
Certainly!
(Associates link supports a local arts org.)
Available in other colors, of course.
Stellar! It really pops!
Wonderful thanks for the link. Its going on my Amazon “glowforge” wish list.
Hey - thank you for your settings! Worked perfect for my keysmart keyholder
