A big cellular thing. Use this as a lampshade for an LED light or as a sculpture.

Many people have printed the bracelets I uploaded so I decided to give you something bigger.

Here's the model on Cell Cycle:

I've uploaded a new version (cellularThing_optimizedForMakerbot.stl) that is optimized for a MakerBot Replicator. The bottom of the model is sliced off to make it completely flat, the thinnest members of the structure have been thickened.
Recommended printing settings:
Shells: 3
Infill: none
Support: none
Feed Rate: 40 or less
