I don't always like the idea of single big buildings, several buildings feels more industrial to me.
I tried to make it fairly walkable.
I also realised that after finishing it, that I also need to send the output to a train to take to a future plant for Modular Engines, but I didn't leave any space for the train.
Honestly, this is a lovely little factory. I am a big fan of multiple buildings as well, especially when they all feel well connected like yours. What's the production rate for your factory?
Supposed to be 8.5/min, but I used manifolds so some of the stuff is still filling. Even so I spent so long on making things look good, it already filled up the storage for upload.
That'll be a pretty good rate once it's fully warmed up!
