So, the March Madness 1 program a day challenge is in full swing. Here’s my contribution. Its not much in the way of code, but there definitely was coding involved in writing the scad file for the doorknob. Yup, its a programmatically generated and then 3D printed doorknob for the NYC Resistor front door. Made with OpenSCAD, QCad, and my MakerBot. Oh, its open source too and you can download it from Thingiverse.
