It is finally complete - 45 SPM 7 science 1 roboport facility. No blue belts were used, or robots. (Except to build the thing)
This monstrosity of spaghetti consumes 6 belts of iron, 1 belt of steel, 6 belts of copper, 2 belts of coal, 1 lane of bricks, 1 pipe of oil and 1 pipe of water.
It spits out 45 science per minute. This is enough throughput to earn all of the achievements and works really well as an 8 hour acheievement blueprint - plop it down and try to feed it - win. I haven't messed with the oil much, so light oil is lacking for rocket fuel unless you turn off the crackers....
I designed this because I have an affinity for compact spaghetti. Enjoy!
Best suited to plop down at the end of the bus and let robots build it.
