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 made by extruding and twisting the Koch Snowflake into a Christmas Tree. This is the same fractal construction used in the [Fractal candy dish](https://www.thingiverse.com/thing:4067943). Vase mode is recommended. 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 modified. For a 50-150mm tall tree, three iterations seems to work well, but for larger trees additional iterations may be nice. The tree itself is highly parameterizable using the SolidPython file. The parameters are explained in the function header: ``` 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 ): ```
