As you can tell, I'm not a huge fan of the Alien movies... ;P

Can print without infill but I don't advise it, use about 5%, use supports, rafts is optional. There is little support to remove, nothing was particularly tricky. This is pretty much my mini test for a full scale poseable facehugger which I'm working on.

I kept the poly count low on this one, I tried slicing it at 2 million poly's and it just bombed out, so I had to go back and simplify the mesh even more, I figure 25mb odd isn't too bad, I printed mine at 8cm high.

Enjoy!
