The [3,1] knot I printed required more material for support than the print did, but it came out nice in the end. I designed it to fit a 12.7mm steel ball I had extras of from a Geomag set. Since the knot is toroidal, the ball freely rolls around the inside without falling out.
I included a couple of other example knot STLs in case you can't run the script.

I'm guessing by "base" you mean support structure? Skeinforge has an option for support (there's a checkbox in ReplicatorG for it as well), which is what I used on knot31. Makerbot also has some useful how-to articles about it on their blog.
Can I ask you something 8-) , your second image show a base that was created using a script right? Sorry for my question , i don't know if I understood ...
So I like that because I just started printing and I have some Action figure modeled on Zbrush, that I want to print, and they need a struct
ure to be build ..
For this wolverine maybe I could print in pieces but for a small scale for sure needs a structure.
Congratulation for the model! ;)

There is a vertical stretch parameter that allows the knot to be taller (to make supportless printing possible) while maintaining the circular cross-section. There is also a thickness parameter that flattens the bottom of the STL to make a base area where the print can actually stick to the build platform.
The one lame thing about scripting this versus the OpenSCAD version, is there's no guarantee your mesh will be manifold. Basically you have to look at the plot and adjust the parameters so that it doesn't self-intersect.
