I was very impressed with my newly arrived AMS-HT and decided to order another while it’s on sale. 
I had looked at various printable stacking models, but hadn’t realized they would not work with my P2S.
Can anyone link me to a basic model that will support one AMS-HT on top of the other? I figure the sides may have to be in 2 sections because of height needed to open and load the lower unit.
Or a sliding plate for the lower AMS-HT
