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.
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.
Its true only one type of curve :-(
You just have to activate the other curves in your addons under TAB Add Curve.
Sorry and thanks for it!
