I use Qubicle to make the voxel models. Some pre-made models here. I use the demo version on Steam (because I'm a cheap-o). You can get the full version for $20 or something.
Fine, you don't have to yell. Also, are you done with the secure-o-bot model?
Bad news: The model took a really long time, and once I was almost finished, I came back to see that the file was corrupted and I completely lost the model. ;-;
I have some stuff for you aware!
