Maybe I've been spending too much time down the UFO/UAP youtube rabbit hole……
Ive designed the model to be printed as is, so it is hollow(2.5mm wall thickness) with the inside not following the contours of the heads and pyramids. I would imagine it would print fine in vase mode though. It's 160mm(ish) tall and took about 10 hours to print at 50mm/s.
Ive printed mine in Eryone 2 colour silk PLA, I've not quite got this filament printing perfectly with a bit of random whispy stringing and the starts showing up a bit too much.
The author marked this model as their own original creation.
