Hi. I like this mod very much, someone suggested it for me and it's great, I just started using it.

In the image you can see that compared to the assembly machine, the Hydraulic plant is a bit too big in the sense that it goes out of the yellow square when hovering the mouse over and it overlaps with the inserter underneath it too. Maybe you can change the size of the spires to fix the square better?
Thanks, great mod.
