That's VERY similar to stands made by Salamander Designs https://www.salamanderdesigns.com/racks ... io-stands/
except that the TNT version only uses three rods.
Interesting in the TNT FAQs that he says this:May I use the TNT-FleXy Table with my analogue turntable?I think it is not the best turntable table available. If your turntable is a cheap component you may use the FleXy with no fear For more "audiophile-oriented" turntables I'm working at a special shelf that may successfully be used together with the FleXy Table, so stay tuned.
[I don't see where he has posted this special one yet.]
I don't think Home Depot will drill the holes for you, and that is a critical step, so be prepared to take some time with that. I'm kind of surprised that the TNT webpage doesn't spend much time describing the drilling process. My advice would be to align and clamp all the shelves together tightly first, and then drill the holes through the whole stack. That way you are ensured to have them aligned together. It may be difficult, though, to find a drill bit long enough to go through the entire stack. A drill press would be HIGHLY recommended for this step since you'll want those holes to be perfectly perpendicular! Using a hand-held drill, you might get off a few degrees.
