Towards the middle of the DLC story, there is a puzzle where you need to build three bricks. If you build all three of these bricks in one visit to the circuit board, you get the achievement.

It's the level where you have to open the first big slide door on the right.
You have to recreate 3 parts. 1 Brown cube, 1 brown tube and a tiny blue pyramid.

(It is not the slide door with the red light)

If you recreate all 3 items at the same time, you get the achievement.
