Petrol station Project

I want to build a gas station in parts, to put it in a scale model car. if anyone has any ideas or has seen material gas stations, I would appreciate some links ..

I have start printed in 3D, the idea is to print directly without supports, the two sides and glue.

Well after a little more than design, I've finished the most important parts of a gas station. In the end I miss some changes that I think are better, I added an independent supplier, a little bigger, and I modified columns. Just
