The file 'Bioform Stool 3D Printer Model' is (STL) file type, size is 483.7KB.
I made a small research on biomimicry and published a new article about it.
Also made this stool model to test Solidwork's organic modeling capabilities.
Seems like they work well.
A low rez version of the stool design is downloadable here.
