Hi People :-),
I am experimenting with the semi transparency of PET-G and geometric spiral forms.
This is one of them. At home I have a Led armature that can change color (I made that a while ago).
Because the 3 led are in offset with each other, you get strange and amazing light / shadow forms on the wall. :-)
You can also use Vase Mode in Cura. This is much faster. These prints have extreme long printing time otherwise. I had printers running for 1,5 to 2 (if you do not use vase mode).
