A collection of terdragons.
The terdragon was first described by Chandler Davis and Donald Knuth in 1970 in the Journal of Recreational Mathematics. Fractal curves, similar to the terdragon, are the basis of broad band antennae. Without them cell phones would be much larger.
Like the dragon curve (see thing:66733) the terdragon can be generated in stages. Partially parametric openSCAD code to generate the first 7 orders of the terdragon is provided. Lines that generate the curve are replaced by rectangular blocks whose dimensions can be chosen.
Stl files are provided for terdragon curves of degree 2, 3, 4, 5, 6, and 7.
The openSCAD code that generated the files is terdragon_3d.scad.
