Koch Snowflake OpenScad Generator

I wanted to create a 3D-printed Koch Snowflake for Christmas but couldn't find a model that fit my needs. Therefore, I created this simple python script to generate Koch Snowflakes for me. This tool can generate nice Koch Snowflakes using Python and OpenScad. You can check out some examples here.

How to Install

1. This project uses poetry install it first.
2. Clone this repository
3. cd <cloned_repository>
4. Run poetry install
5. Use the tool with poetry run koch_snowflake

How to Use

Usage: koch_snowflake [OPTIONS] OUT_FILE

Options:
  --size FLOAT                  Side length of the initial triangle in mm.
  --iterations INTEGER RANGE    Number of fractal iterations. More iterations
                                yield more complex snowflakes  [0<=x<=20]
  --thickness FLOAT             Thickness of the snowflake in mm.
  --with-hole / --without-hole  Whether you want a hole for hanging the
                                snowflake.
  --hole-radius FLOAT           The radius of the hole in mm.
  --hole-clearance FLOAT        The clearance of the hole to the outer
                                perimeter in mm.
  --help                        Show this message and exit.

How it works

1. Python and numpy are used to calculate 3 Koch curves to form a triangle
2. The resulting points are then used to create OpenScad code using openpyscad
3. You can render the resulting scad file using OpenScad and print as usual
