Ring Light

LED Ring Light. I use it as a camera/selfie light, but it could be used as mood light as well.

Print both the base and cover. Glue or stick the led strip to the base, then cover with the cover. Two pieces should fit seamlessly, just need a bit of glue. Any LED strips would work, I used generic LED from Amazon. I recommend using white PLA to print the cover to diffuse the light.
