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.

I printed first file with my UV resin printer.
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.

The first file is optimized for UV-resin printing --> file "v3"

I updated the file by a version for standard 3d-printers --> file two "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 rafts 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 .

Please check the pictures of both versions for the differences.

+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.
