I received my 3d printer a few days ago (Pirate3d Buccaneer from kickstarter) And got to printing stuff straight away, well straight away after I figured out I hadn't put the filament in far enough... twice.
So the first thing I printed was a couple of quickly made chainsaw fists on Google sketchup. Just to see it in action.
They turned out okay but that was mostly due to my files.
As I also got Imperial assault for my birthday, a month gone now, I started looking for Star wars stuff on thingiverse. I found a Rancor!
I printed it off over about 40+hours of printing time.
Here's a pic next to a Bright wizard. Didn't have any Imperial Assault figs handy.
The sculpt was a bit soft in places and I need to file down some areas. You can see how many pieces it was in originally. That was due to it being a posable toy. I may reprint at about 67% (which will happen all in one print) to get a better size for Imperial Assault but I'm happy with this guy. He's a little taller than the AT ST from Imperial Assault. Don't actually know how that scales in the star wars universe.
