This is the stylized lobster from www.123Dapp.com.
I split it into parts and oriented them for easy 3D printing. The claws, legs and antennae need to be glued to the body. I have included connector pins to attach the head and tail, but they didn't work at the small scale I used, so I just glued them too. I painted the eyes with black gloss enamel.
I've included the Meshmixer file for reference.

I started with the Autodesk Premium Lobster from www.123Dapp.com and used Meshmixer to split up the parts, make them watertight solid bodies, and orient them for printing.
