This is loosely based on a design by Popcop12, but is a completely new design as I has trouble trying to print it.
There are a few versions that make the same tree. The easy and almost support-less version is in 3 pieces - the tree in 2 pieces and the star. With the tree split, the bottom of the tree can be printed upside down without supports.
The only supports that might be needed if printed in 3 pieces are inside the bottom of the tree top, and either side of the star support, as I printed this lying down.
Merry Christmas.
The author marked this model as their own original creation.
