I found this old thread and there was a picture of a tube rack for storing a refractor on a bench (pic and idea by Houndsbourgh) https://www.cloudyni...ng/page-2#entry
So, in my winter bordom I made one for myself for my AT115EDT. Went to Lowes Hardware store and bought the tubing and connectors all for less than $20.00. They can be sized based upon your needs. Works great and I hope this may help others looking for a solution.
Hope the attached picture worked.
