It was clear from the first few seconds that my first try was a charred mess, so I aborted and tweaked the design to better account for the kerf, but I think I overcompensated. I’m also not sure about this paper. It is a scrap of thick photopaper from the large format printer at work, and it appears to have a shiny lamination on one side that might not be the best laser fodder. Will try again this weekend.
UPDATE:
Almost there!
Just right.
A part of me likes the “almost there” version better.
