Hi everyone, I am thinking of building my own rack that will support up to 60 tubs, only issue is that I don't have a lot of tools anymore and would like to make the rack as effortlessly as possible because I severely injured my back so that's another impediment towards getting this done.

If anyone has any plans/blueprints for cheap, easy to assemble DIY racks I would be VERYYYYYY grateful. Thanks!
