I received my test tube stand from Amazon, wonder what HSA think about that 
Anyway it holds David anyvape, Kanger Aerotank and protank 1. Doesn't hold the big nautilus. I'm going to fill it with aerotanks all different flavors labeled with avery sheets from my laser printer.
Here is the link: Amazon.com: Round Test Tube Rack Hold 24 Tubes up to 20mm: Industrial & Scientific
