This is the 3D version of the Pythagoras tree (the traditional 2D version can be found here). The cubes are placed in alternating order i.e. first we put a cube on the left and right hand side on top of the base (in 45° to the base and in 90° to each other) and in the next level it will be a cube at the front and the back. The result is a nice little tree.
Similiar to the 2D version I had to add some small extra shapes where the cubes are touching each other to get a solid output.
Print with 0.2mm is sufficient and I suggest to use organic supports.
The author marked this model as their own original creation.
