Thanks to Delta Wiskey for sharing his remix and to idig3d for the original tree design (https://www.thingiverse.com/thing:1913982).
Printed with clear PETG in vase mode at 0.2mm resolution. New smaller base and 3 tree heights.
Tea light is about 1.45in/37mm in diameter. Used super glue to secure tea light to base and base to tree top.
Update: Check out the new Gift Box for the set of trees and spare CR2032 batteries.
