Hilbert Cube

cults3d

While searching for innovative designs to print using water-soluble PVA support, I decided to attempt creating a Hilbert Cube: http://en.wikipedia.org/wiki/Hilbert_cube After struggling and failing to create it in OpenSCAD, I found a workaround by writing a Ruby script that generates OpenSCAD code. This script can produce 1-3 iterations of a 3D Hilbert curve. I borrowed code from Thomas Diewald's Processing script at http://www.openprocessing.org/visuals/?visualID=15599. However, upon closer inspection, I realized my creation was not actually a Hilbert cube since the shape is not one continuous curve. Despite this, it looks amazing and would be extremely challenging to print without dissolvable support. It would be fantastic if someone more skilled than me could develop a proper parametric Hilbert cube generator. During my search, I also discovered a stunning curved Hilbert cube by Carlo H. Séquin at http://www.cs.berkeley.edu/~sequin/X/Hilbert_Cube/. I resized it and created a support model, but I'm unsure about the license terms. Hopefully, he won't mind me sharing his work here. The issue with this model is that its curved design makes it more difficult to print.
