Nice christmas tree decoration for covering standard LED tea light candles as shown.
good gift idea.

Scale the design to fit your LED candles, if necessary. The current thing inner diameter ~ 3,7cm. height is ~ 11cm.
No toy, sharp edges.

Use rafts and support and a low or no infill for a nice light transparency.
If printing in resin, don´t forget to hollow it (walls 1.2mm) and place some small holes as shown in picture.

I updated the file by a version for standard 3d-printers --> file "optimized":
Lowered the star on top, so it don´t need support and the cone inside is maximized, the inner structures don´t need support as well, due the new inner design. The bottom layer is leveled. Use brim for better 1st layer adhesion. Infill of my sample print is 8%, two walls, 8mm raft. I think less infill might possible. Printing time ~2.5h .

NEW: I attach an easy print-version without the star holes in the socket

Latest: New version "hollow Star" with better brightness on the top of the tree
Currently, I print a test of it.. without any infill for best brightness...see the dark PIC. Print without infill is possible. I will optimize the inner structure soon.

The design is made in Tinkercad.
