The GHelix Bangle: 'sketching' in Grasshopper and 3D prints

The GHelix Bangle is a reinvention of one of my earlier Rhino/3D print designs, based on the curious topology of the Moebius strip.  Although it already exists as a Rhino file, and has been printed out on a number of occasions, it's a tedious and time-consuming process trying to make changes to it.

I spent a day, recently, embedding the original,…

NACA series 4 aerofoil generator

This has already been posted on the GH forum, but I suppose it should have gone here instead ;-)

I've been playing around in Rhino 6 recently, and put together a GH definition to generate NACA series 4 aerofoils. It's based on the equations and methods set out in Abbot and von Doenhoff’s classic student aerodynamicists’ text, Theory of Wing Sections. NACA's 4 series aerofoils are now rather old (they were developed in the thirties), but they are still useful for low-speed applications…
