I’ve a had blast the past week or so 3d printing some snowflakes. They are for the math department for decorations around the holidays.
I’ve been using Mathgrrl’s (aka Laura Taalman) snowflake ornaments (Thigiverse thing 195032). She’s since customized the design here: http://www.thingiverse.com/thing:570339.
I also had a blast printing some of her fractal snowflakes from the Snowflakerator snowflake machine found here: http://www.thingiverse.com/thing:1159436.
