Thanks Makies for the great Jack-O-Lantern! There were some problems with the mesh not being a solid, so I cleaned it up a little. I had to remove the Makies name from the bottom because it caused a lot of the problems, sorry!

I wanted to be able to union/subtract from this model (going to fly this baby around on my tricopter for halloween!) but I couldn't do it without the model being manifold/solid.

Feel free to use this model if you need to mess with it, I've included the sketchup file too if that helps!
