Well the bits were just sitting there guilting me anyway.
I'm trying to do a set of corridors -> room -> centrepiece in cycles so as to keep the interest up and keep a balance of pieces. Also I paint these in batches to have some kind of consistency so these are all going stay unpainted while I build up the room + centrepiece. I have some hopes of taking this to salute again for 2019, and necromunda + rogue trader are firing neurons off, so we'll see where it goes.
Five more pieces (end, T, 1, end, 3)

I've solved the corridor door problem now thanks to U-channels and Fenris.
No door, open door, closed door:

Components + magnetised theme pieces (to 40k it up or down):

Next up a flooded section, because half-life.
