Nativity Tea Light

I'm new to 3D printing and learning lots about this process and 3D cad. So I thought this would be a good little project. I wanted a tea light based on some plastic wine glasses I have that would stack for easier storage, and moving when setting up on tables for the church dinner. Also my first time using translucent PLA. I get a bit of stringiness around the base of one of them which I can live with for now, but I'm sure someone more experienced can adjust to avoid that issue.
