Need to improve a drying rack for clothes.

The rack I'm talking about is called, STORAGE MANIAC Sweater Drying Rack (google will show first amazon result).

I purchased this and it works as intended. However, the problem is loading clothes on the middle and lower portions of it. It isn't meant to become unstacked easily. You first start by placing the first 1/4 of a shirt on it, then you spin the whole rack 180 degrees so you can reach the shirt to pull it all the way into position. This sucks and strains your knees.

A better product would be a rack that has slots, and removeable "cassettes" that you can load a shirt on at a nice standing desk height, and then insert the cassette into the rack.

This product doesn't exist but I want to create my own. Can you please give me advice on how to make one? I do not have a ton of tools (really just have a drill and some hand tools). But I am thinking that pvc elbows, tees, and connectors are easily available at hardware stores. Is pvc pipe going to even be strong enough? The plastic tubes on this Amazon product do not flex or sag.

Edit: After I finished typing this, I look over to my right at my Ikea metal shelving rack (Google: Omar). Possibly I could craft a cassette style rack out of the 4 metal posts. But I just need them to be 27 wide and 27 deep (so no Ikea shelves are like that). But maybe they make custom parts for that style of shelf. And then do pvc and mesh net cassettes.
