A while ago on TMP, someone posted an idea to cut down the blue electrical junction boxes. I had a bunch of them sitting around and decided to give it a go. I went out the garage where I had a wood band saw and had at it. I was very pleased with the results. Be warned it requires a steady hand due to the sloping walls.
I've included some minis for scale reference.
As you can see things worked out well. More to follow
