This device is a very simple solution to a simple issue.

After removing and cleaning the metal sheet, I need to put the sheet somewhere for the methylated spirits (rubbing alcohol) to dry. If I put it on the bench, it might attract dust or debris underneath, creating a potential thermal barrier or uneven spacing between the heat bed and the metal sheet. And I don't want to allow moisture to be trapped between the heat bed and the metal sheet either.

Now that I have this device, I simply clean the sheet and put in on this stand for a few minutes to dry. The only contact the sheet has is four small tiny points in the stand. Even though it is not very big, where each arm is only 150mm (about 6 inches) long, it folds away for easy storage if necessary.
