Natural Gas Meter

I am building a diorama and wanted some common utility items you might find at the rear of a building. This is a natural gas meter, I also have a gas valve which I will upload as well. This should be painted in grey and have one gas line going in (which comes out of the ground) and another coming out (which goes into the building).
I have not printed this item yet, so please let me know if you do how it turns out.
