A mount for LG UHD displays for use with Continuity Camera in Mac OS (Ventura or later). It's designed to fit an iPhone of any size in a case - without a case it'll be a bit loose.
Make sure you get the right one for your display as there's two shared here. I've been told the 27UL850 model also works on the 27UH88 display.
The 'springloaded' phone holding part was heavily inspired by yejj97's design, and was adapted for this model with their kind permission.
