Shipping containers are cool. Here I drew one in Sketchup. I used a corrugated metal texture and the dimensions are 8 x 20 feet floor and 8.5 feet high, what’s called a TEU (Twenty-foot Equivalent Unit).
I’ve decided to table Blender until next month. It turns out that Sketchup is useful for more than 3D printing, it can express engineering ideas in a very crisp fashion.
