While they do fit a 40mm base, the model is not even as high as space marine...

I've currently printed these in 2 sizes. Even though these are for a sci-fi campaign, they'll make great monsters/demons for fantasy, which is what I'll use them for. The archer is 30mm scale. The smaller ones are about his height, and printed out fine.

Done smaller than the last set. I also painted them with speed paints and the slap-chop method.
