So I decided to build another rack. After having searched for forever, I finally found a company with decent prices.
For a full sheet of 1/2" thick XPVC with cuts and shipping it cost me $184. From Multi-craft plastics.
I decided to go with an open air design that I found on ssscales. This is a 7 slot rack that uses both 12qt., and 28qt. sterilite tubs.
So without any further ado, here it is.
