Laser radiation sign with LED

thingiverse

I'm working on a cool project in my workshop. My kids like to drop by and see what I'm up to, especially when I'm using my laser cutter. Today, I decided to add a personal touch with a laser radiation warning sign that really stands out - it's lit up with a bright red LED strip. When the light comes on, it's clear: "Do Not Enter" - my kids know better than to venture into the room when the sign is glowing.
