what type of pipe can i use and how do I install it to get the same result (or close to it) as in the attached picture?

I have a small, portable braai that I used to keep on a convenient brick pedestal, but now I have moved and I don't have such a thing anymore. I need to either build or buy something to put it on, because it is so low that it can't stand on the floor if we want to use it (about 40cm high). Would appreciate any advice.
