A good solid door. On any space station, it’s the only thing standing between you and the dark, dangerous, cold of hard vacuum. Sad Brick‘s latest model focuses in on this essential part of any space facility — and this door certainly looks like it can take the pressure.

The vehicle and the little droid are cool, and I like the details and texture on the walls. But the door itself is the undoubted star of this show, with huge hinges and the use of slope bricks suggesting an appropriate heft. This is clearly a serious portal — not for casual opening.
