CNC DIY Etched Lighting
I’ve had these 3/8″ acrylic disks sitting in my cruft boxes for a few years now – they were the excess material from a waterjetted 2.670 robot part, and naturally my packrat nature kicked in when the professor offered them up for free. I immediately had the idea to etch patterns into the surface that would glow when the disks were edge-lit, but lacked a dremel or any workable knowledge of g-code to make the CNC mills do my bidding. My alternative effort to use a hand drill with an ordinary drill bit as dremel failed spectacularly, so I shelved the project.
Recently, however, I discovered that the CNC mill at the hobby shop can take DXFs directly! Thus, my CNC DIY etched lighting lives again. I’ll eventually make 5 or 6 of these and string them along my walls for ambient lighting, but I wanted to show off the first two out of the etcher.
