It would be more efficient to make just an “L”-shaped jig, and lay several lighters side-by-side. Combine the graphics into one bitmap, and the machine can do several in each pass.
You’d need to fiddle with the spacing to ensure they are all perfectly centered, but testing on cardboard, for example, wouldn’t cost anything. Instead of engraving the entire graphic for the test, create a box that perfectly borders the design, and use that to get the spacing right.
the engravings were all individual and i didn’t have all the designs at the same time so it worked out pretty good with this jig, maybe i’ll do another one for like a whole tray of them
