Truly beautiful.
Just two suggestions:

The first is purely mechanical: the straight pin, without a draft angle, makes the assembly more stable and more precise; a gap of 0.1 - 0.2 mm should be fine for all materials. It could also be extended by a few millimeters.

The second concerns the tree-topper attachment: a support tube can be helpful to stiffen the tip of the tree and help it stay straight. For now I made one out of cardboard, but it could be useful to include it among the print files.

If i find the time, I might try making a remix or send you the drawings.

Other than that, it's a really top-notch, it's fantastic.

Fantastical tree topper. Beautiful.
Printed with bronze PLA silk, organic support with overhang threshold 50°, just to give a solid base for some elements.

I printed this in Sunlu PETG, Glow Green, Glow Red, and Transparent for the core and top spike. The star doesn't glow the way I'd like but that's from a lack of light on the glowing spikes. Still looks really nice being red and green

What a Beauty. Mi family loves it. Printed in glow PLA. I should have scale it a little or may need a bigger tree xD

Nice optics.

The connectors on the core are bad.
Even printing with supports this is gambling if they‘ll hold or not especially when removing the supports.

For the core a 2 part design would help printability.

Overall nothing glue cant fix but not a 5/6 star design tho.

can u give me instructions on how to assemble it

What a beautiful model. I've used mine two years in a row. I stuffed some thin LED lights inside and wove some through the spires with great effect.
Unfortunately, it didn't survive disassembly this year and will need some spares printed.
I'd love if you could upload a STP of the core so I could remix to incorporate some @mcurtis improvements with the stabiliser and split down the middle for easier print without supports but without the need for individual LED's in each spire.


I've tipped you for your great effort.

@Robdanig_1701 thanks so much! I've attached the STP files for you, hope that they work nicely!

Beautiful design. Printed with 90% in „das filament“ marble white.
