Designed this to mount the Bambu Lab P1P iPhone Holder https://www.printables.com/model/415654-bambu-labs-p1p-iphone-holder to the right side of the Robust AMS Riser https://makerworld.com/en/models/16530#profileId-15347. It's not perfect but it works for me. The glass lid on the P1S still slides in and out but this does block the shelf if that's something you use. I use an LED riser with vents between the printer and Robust AMS Riser so I don't move my top glass.
