DNA, B-form base pairs

EDIT: I have included updated models. The pins are slightly thicker, making them more robust when printed at a smaller size. I've gone ahead and added the A-form DNA versions as well (GC-a and AT-a).

I was working on a blender script to automatically pin ball-and-stick nucleic acid models. I tested it using an idealized B-form DNA model (Coot).

Workflow:

Coot (model)
PyMol (ball-and-stick representation)
Blender (automatic pinning script and unionize)

These were printed 0.2 mm, sup
