My take on Spider Jerusalem's bowel disruptor from the Transmetropolitan series. Images to follow...
Also I've added the rhino file for anyone who feels like improving on the current design. At the moment this is just a prop with no moving parts.
Print out the full file with support or print each of the components separately (two of the center twisting dial) and glue together. I had to scale the components by 0.6 to fit on the replicator's build platform.
