Fractal tree

thingiverse

This is a modular fractal tree that you probably need to glue together. Two basic elements are set up vertically to build the tree. With each layer, you need to use 4 cut parts and 4*i standard parts, where i=0,1,... is the index of the layer. The time you need for this print is proportional to h^2 where h is the height of the tree.
