Let me start off by saying that my layout is a “caricature” of life, spawned out of my head. Any similarities to the real thing are merely a coincidence.
That being said, I had a small area where I wanted an oil depot small tank farm. The tanks are made from 4" PVC coupler and cap glued together. The ladders and railing on the tanks are 1/2" wire mesh (hardware cloth). That is where I was stuck before I got a 3D Printer.
The 3D printer was less than $150 including free shipping, http://r.ebay.com/MsizlX, so I jumped on it and it gave me the inspiration and needed materials. I made all the pipe fittings, tank hatch, stairs, platform railings, gate supports, and pallets. The pipe is 1/4" ID PEX (almost 1/2" OD)
The chain link fence is made from 1/8" rod and metal mesh screen shown below. The lighting is LED, overhead lights made from 1/8" brass tube and scrap plastic.
Here are the results.
