This is absolutely not in any way my work. This model is by Oliver Baker. I found it on the reprap site http://objects.reprap.org/mediawiki/index.php/Tux

All I did was convert it to a .stl that replicatorg doesn't hate.

Edit: I had some trouble with it recently. I ran it through netfabb cloud and that seems to have cured it of weirdness.

This thing prints pretty well though it needs support and a raft or it will be a penguin sitting in a pile of spaghetti.

scale it up till it looks good.
