So I got tired of my cans being all over the house and decided to search for a rack that would hold multiple pairs. I found some options on eBay and Amazon but nothing that I was crazy about. After a quick Google image search I found a good solution. A trip to Home Depot, ~$30 in parts and five minutes in assembly time and this is the result. It works great. Easily fits 3 pairs. Funny thing is I did find this exact rack on Etsy for $30 plus shipping after I made mine. The one on Etsy only holds one pair. It's ugly but super sturdy. The size is 12 X 10. From the pic its easy to see what parts are needed. Schedule 40 black pipe.
You can do 1/2 in. or 3/4. This one is 3/4.
