I'm not a streamer or any big name like that, but I did make 2 bases that I was particularly proud of. I think the 5k one is pretty cool looking, probably a shot of the 292 belt wide bus. The 1k burner base would probably be either the blue circuits or satellite.

If they aren't good enough, I won't be (too) offended, but wanted to throw it out there. If they do strike your fancy, I can go back and use the screenshot command to get a hi-res image for you.

Thanks for the suggestion! Of course, you don't need to be a streamer or anything. I'm trying to represent all parts of the Factorio community. I will have a look at those bases. And if I want to add them I'll only need the save file, which I see is supplied with both. :)
