What about having a MP Room that is two levels high as designed with a staircase prebuilt inside it so no ladder and could stack them and have a staircase connecting all levels?
Why not have a central room Fab station with storage medium kinda like a bioreactor but you just add the mats and they get stored up to a max point like 200 boxes of mats so you still have lockers to hold things outside you just have a big power hun…
