Description

These are two molecular models of a lambda bacteriophage Cro protein and a region of DNA to which it binds. As long as this protein is bound to DNA, the phage will remain dormant. Stress triggers degradation of this protein and re-expression of the phage.

The narrow towers don't quite print right on my bot, your mileage may vary. I wish I'd made them every so slightly smaller so they fit better, or had some sort of sand-blasting polishing tool.

For a fishtank, I would suggest openings in it that would allow a small fish to escape a big one.

has the appearance of coral reef growth and it looks like it would make great fish tank decorations. sweet

Try turning on the cool feature in your skeinforge settings.

cool is on with 10 seconds, the problem is that tight curves accumulate too much plastic. I can't figure out how to tune this, since it is only the tight curves, and decreasing plastic overall causes poor print quality elsewhere.
