Filling space in a mech torso piece

I've found this build while optimising the space in my mini mech. I don't know if it was already discovered before, I've never seen someone trying to fill this space. If this ur question, no it don't seems to stress the white piece, it didn't need to push with force. Have you ever seen this technic before ? submitted by /u/Right_Promise7925 [link] [comments]
