Last update before Thanksgiving

I haven't had much time to commit to the UCSDS, but I was able to complete the hanger bay door, add the command center, and add the prison level to the main structure. 

I'm hitting snags with the lack of custom blocks that the set calls for, but I push on with what I can, and I'll circle back to tidy up the loose ends when I find the parts.

Have a safe and fun Thanksgiving break!
