Floating nightstands aren't as wide as traditional stands. I created this to give you a bit more room. I use the top shelf to site my Nest Hub Clock and cellphone. The bottom shelf is for whatever. The “hook” which just slides over the edge measures 12.2mm (the size of mine). If you give me the number, I can resize it… or you can just print out a shim to slide between. Added 10mm test strip, so you can see how it fits before printing the entire thing.  Grab some “wood” PLA and print!
