I made this base for xSteve's Christmas Tree 2024; https://www.printables.com/model/1067899-christmas-tree-2024. You will need to print the Christmas tree with 2-4 bottom solid layers. I printed most of my trees with 2 bottom solid layers. I think cut an 1-½" hole in the center of the bottom of the tree. I then glued this base to the bottom of the tree. Insert your tealight, I used these, https://a.co/d/2QHT0AL.
