Transparent ring cover for WS2812 24 led module

I have bought a round 24 led WS2812 led module from Ali express. I want to make a light for my music stand. Of course I needed a transparent cover for this. I designed this thing for transparent PETG. My first attempt works great. The edges of the ring are 2 mm. The thickness of the front is 0,4 mm. For my bambu printer I have used a smooth build plate. I used install.wled.me and an esp32 to make it light up.
