DNA Sculpture (Parameterised)

thingiverse

This model is now available for purchase in various materials through Shapeways. Printed using a Makerbot, there are two versions - "Right-Handed" and "Left-Handed" spirals. The Right-Handed corresponds to native B-DNA, the active form in most cells, while the Left-Handed represents Z-DNA, the generally inactive form. While not 100% accurate, both can be corrected with adjustments to the script for advanced machines. For more information on accurate DNA structure, visit http://en.wikipedia.org/wiki/Z-DNA#Comparison_Geometries_of_Some_DNA_Forms. OpenSCAD file provides customization options including base and backbone shapes, spacing between strands, and rotation. Don't forget to post your creation on Thingiverse after printing!
