Snowflakes from Gravner-Griffeath simulation

thingiverse

Martin Krzywinski has created an extraordinary collection of snowflakes using the Gravner-Griffeath simulation algorithm, which can be accessed through his website. However, these snowflakes are merely two-dimensional images. You can now convert these 2D snowflakes into STL files with the help of a javascript webpage. To do this, you will need to obtain the name of the specific snowflake from Krzywinski's site and then use that information to retrieve the data from his website, ultimately generating an STL file. All the sample STLs attached here were generated using 8 levels, but it is likely that any STL files beyond this level will be too large to be very useful. I have also created a Python script that performs the full Gravner-Griffeath simulation if you want to adjust the parameters. This script generates both STL and SVG files. Martin Krzywinski has recently added a link to my STL generator from each of his flake pages.
