A two tower facility for the manufacture of white cubes. All colors and anti-matter in, a bin for the final white cubes, and drop boxes on each end to drop off any excess materials from your inventory. 15 individual labs to start, scalable up to 225 labs with stacking upgrades. Belt or ship the white cubes to your research labs. I also have a production and research complex build that expands on this one. https://www.dysonsphereblueprints.com/blueprints/white-cube-production-and-research-complex-for-full-belts-of-each-color
