Hi, im not using plexiglass, its polycarbonate, its better then plexiglass, much more durable and plexi is rolled material so it have some streses inside. Its 6mm thick so all light from led strip can go inside, im cutting it on my table saw and and final cutting and carving it on open builds OX cnc( 2.5D milling machine, you buy it as kit and build it by yourself), but again, you can draw motive on polycarbonate and engrave it with tool like dremel by hand. You need to polish bottom side, thats done with sand paper to 1000 grit and then polished with torch.
