I used my Cricut to cut a medium chipboard mock up of the Maxum Petroleum annex. I had to really compress the depth. I hadn’t intended to make this structure, but was faced with a large open area that made no sense. The structure will also have a series of tanks in the front of it when completed.
I’m considering using a styrene skin mounted to chipboard. My thought process is that it will provide the structural rigidity without having to cut tons of styrene supports.
