Models of Knots

I have made plastic models of the knots up through eight crossings using 3D printing via Shapeways.com. These models are available for anyone to buy from Shapeways.com. Clicking on the "buy" link under an image will take you to the model's purchase page at Shapeways.com, where you can add it to your shopping cart. Within two weeks, your models will arrive.

I made these models by using Mathematica's KnotData feature to produce Surface Evolver files of the central curve, then my Evolver script edge_tuber.cmd to tube the curve, and then my Evolver script stl.cmd to write the STL-format file that Shapeways.com needs.

The models are all scaled to be 10 cm in size, and have solid 3mm diameter tubing. The default material is white plastic, but you can pick other materials.
