This is attempt #2 at creating the ultimate apex predator: a metal flexi-rex.

The secrions are joined together through little gives next to each chain segment, which should allow the metal to flow through to the bottom and fill everything with gravity. This will be a vacuum assisted casting, so any air bubbles sound be pulled out.

My first attempt looked like this- an absolute mess. 

I had two models joined together in one mind hoping to get at least one good one. But I had complications with the vacuum so it didn’t fill.
