The makerspace is located upstairs in 4E 1.27. To get there, enter 4E from the parade, and go straight ahead through the lobby. Continue going straight through the hallway until you get to a staircase. Go down the staircase to the bottom. Turn right and head through a corridor with lockers on either side. As soon as you exit the doors to the corridor, turn to your right, before the staircase, and the doors to enter 4E 1.27 will be there. Head through those doors and up the metal stairs to get to the makerspace.
The area downstairs and the 3D printers there are specifically for internal departmental useage, and are not part of the makerspace.
