I think I’ve figured out what will hold up my tablet forms on the tables. The idea came to me after doing many google image searches on tablet stands. This is an acrylic one which is currently being used in some retail stores:
I like its simplicity, and that it has the rubberized edged which will make solid contact. I also like that it gives the object the appearance of floating. These were surprisingly out of my price range, so I designed my own variation. I am ordering clear acrylic parts to build these. I’ve steepened the angle slightly, but the idea is essentially the same. I will put a circular bead of silicone on the surface to provide grip and minimal float above the disc.
