This is the "Jump Start Base" blueprint by user Nilaus: https://factorioprints.com/view/-KuGj0uUTKl8VpIau-_l However, when attempting to import that blueprint it seems it doesn't work anymore, so I've copied it for the current build as of 11 June 2025. I also upgraded all Assembling Machines to be Assembling Machine 2's. This is completely vanilla with only the Space Age DLC, no other mods. https://imgur.com/gallery/early-game-red-green-science-M9ieOki#xJK9JQU
