Bulkheads and structural details were a main concern, so I did some shopping and dug up some Deathzone terrain sprues:

Electricity outlet boxes, old computer disc boxes (3.5" discs) and printed circuit boards + a couple of bits of computer interior which are perfect for doors. And a tin of Guinness as a storage tank, before I remembered I am avoiding metal - curses, I might have had to get a few more...

A possible transporter (also an old double fluorescent tube fitting...)

New thruster design - slightly defocused:

This is where they'll go - there will be a solid bulkhead behind the circuit boxes.

PVC cable conduit - to be used for corridors leading to open area:

Er...??

(I found my old farmyard poultry set whilst looking for bits - these are around 45 years old!)
Some compartments in the pallet are too tight to get models in - these will be pipe and cable spaces - ideal as targets for sabotage/repair:

An old spaceship model will serve as a fluid tank for the thrusters

Printed circuit boards for floor plates, old disc boxes as partitions:
