Not 3D printable or available in other file formats as it was made with geometry nodes so there is no actual mesh.There is a control node that can be used to control: Tree height, Tree shape randomness, Light density, Tree needle,branch density, Bottom of Tree radius, Trunk Radius and Trunk Height. Everything was done completely with nodes and there was no modelling. You can change the scale and randomness of the model without it looking stretched.Animate the tree with the control node.Light colours are easy to change in the material settings as well as the star shape and size.I used a free HDRI from PolyHaven for all my renders in Cycles to add more realistic lighting.You can also change the colour of the tree itself very easily. The Polygon count can be as low as you want, if you want low poly it is very easy to do so just change the number of needles or lights. Tree trunk is also adjustable for thickness and heightYou can make the Tree as ridiculous and extreme as you want with no limit to the height or amount of lights.I'm having a lot of fun learning and experimenting with Geometry Nodes in Blender so I might upload more stuff with it, sorry you can't use it in any other formats but this was just a bit of fun.Merry Christmas Everyone!
