The idea was that kids in kindergarten would make a snowglobe as a Christmas gift for parents. I think these can be also used as a nice Christmas tree decorations.
You'll need a print of one of the trees a glass vial, cork, glycerine mixed with water, and some glitter. For the stand slice of dryed lemon and badian, these were glued to the vial with silicone hot glue gun. I did glue the star to the tree with Loctite creative.
I do highly recommend using PLA. I've tried PETG which might be okay for the tree, but not for small stars. Especially if you print it at a large scale and can't afford waste. Pictures contain printouts from Prusament PLA Lipstic Red and Opal Green. I did print it on a Prusa satin plate with mk3s+.
Trees require post-processing with a sharp blade. Some imperfections done by post-processing were okay for the use case.

Donated to one of Kindergartens in Mikulov (CZ).
The printout for a local kindergarten was 15 prints of a tree with start and 15 without. And then separate print of 15 stars.
