Slight update. Have the gutters (and chimney) on, stopped the light from leaking through the roof. The gutters were a pain, since I needed to piece them together as I can't print them long enough for the entire length of the roof, and the corners are separate pieces.
There are (3d printed) lockers on the rear wall of the 2nd floor, as per the proposed plans. Still need to find out what sort of interlocking machine was in here. Since there's a "relay room" on the 1st floor, I'm assuming it'll be without mechanical levers, but I want to confirm that.
Have a chair printed to go at the desk in the bay window, and a clock for the wall. I have the rain downspouts added on the sides since this pic was taken, but I still need to connect them to the gutters. Also need to add "copper" flashing to the chimney top. This week will likely be spent filling, sanding and painting the slight gaps between panels.
