White nylon plastic with a matte finish and slight grainy feel.
About this Product
This shape has the same crosslike fractal faces and hexagonal snowflake profile as "Koch Snowflake solid", but also has perfect "Koch snowflake"-profile holes running through it. Which makes it much cooler than its close relative. It's a Sponge!
The shape has well over a hundred thousand faces, and has to be this size to work wih the WSF minimum wall thickness. I'll soon be producing an alternative version intended for the newer hi-res Shapeways materials -- that version will be smaller and cheaper.
