@ekla, those are tremendous! Our own @shaug made some cool stingray leather masks:
but these really take the cake. I can’t wait to see what you do with your Glowforge.
The good news is that the filter will pretty well nullify the smell of the leather you’re cutting, especially if you leave it closed after the cut finishes to let the odors clear. The bad news is that I don’t have a solution to invisibly thicker/thinner areas in leather that you source causing hiccoughs in the cutting procedure.
