Here are a range of Curves that I have created based on the Torus Knot Plus curve in Blender. I use some of these to create 3D printable objects using "Fluid Designer for 3D Printing" by Microvellum. For further details see www.fluiddesigner.co.uk.
Update. Sorry. You just have to activate the other curves in your addons under TAB Add Curve. Sorry and thanks for it!
How to install the addon. I have download the zip file. And from the user preferences i have open and activated. It installed successfully. In the add curve option i can see only the archytas where can i find the rest of the curve (basin, borromean, capareda,etc) present in that addon.
