Fractal Christmas Tree (Kochmas Tree)

thingiverse

My second annual Christmas Tree design. 2017: [Futuristic Christmas Tree](https://www.thingiverse.com/thing:2702395) 2018: [Fractal Christmas Tree (Kochmas Tree)](https://www.thingiverse.com/thing:3234168) 2019: [Hypocycloid Christmas Tree](https://www.thingiverse.com/thing:4022593) The model is created by extruding and twisting the Koch Snowflake into a Christmas Tree. This same fractal construction is used in the [Fractal candy dish](https://www.thingiverse.com/thing:4067943). Vase mode is highly recommended. The model can be lit with a tea light when printed in vase mode with no bottom. The number of recursions for the Koch Snowflake can be easily modified. For a 50-150mm tall tree, three iterations seem to work well, but additional iterations may be needed for larger trees. The tree itself is highly parameterizable using the SolidPython file. The parameters are explained in the function header: ```python def kochmasTree( diameter=100, # Diameter of tree at widest point height=150, # Total height of tree top_twist=180, # Rotation in top part of tree base_diameter=50, # Diameter of base Koch snowflake base_height=25, # Height of tree base base_twist=0, # Twist of tree base top_slices=100, # Slices of top of tree extrusion base_slices=2, # Slices of base extrusion koch_iterations=3, # iterations of Koch Snowflake ): ```
