Pretty straightforward. The Red lines are Score lines, the Black lines are Cut lines. I usually cut acrylic, standard proofgrade acrylic settings work just fine.
If you use mirrored acrylic it helps to flip the file backwards and cut and score the mirror from the back.
I’ve been cutting a ton of these on scrap acrylic and made a post saying I will give them to anyone that has donated to a just cause right now. Zero money passes through my hands, I am still employed so I’m funding the shipping and supplies. It’s going slightly viral, people love them, and it’s raising a bunch for local BLM and bail causes. I suggest something like this.
