Everybody needs glowing stars on their tree. Especially if their light bulbs don't get hot enough to cause a problem with plastic on them.

I used translucent red PLA for my ornament with a 50% fill. I'd assume that any translucent color would work. This ornament doesn't glow quite this bright, but I didn't feel like messing with my aperture settings to get it to come out right. The (standard US) bulbs I use have a diameter of .2" and are .625" long. The hole is sized to accommodate them.
