Headboard shelf with iPhone docking space

I have a bad habit of watching movies on my iPhone to fall asleep so I have created a shelf that hangs on a headboard and has a phone mount in the bottom.The shelf thickness attachment point is ~16mm (5/8"). This is PERFECT for a living spaces ALTON CHERRY headboard. I will be adding more sizing in and if you comment on a size you need that I will create it. I'm trying to think of a way to keep the simple look of the shelf but allow for variability in the attachment point. The phone cutout is built for an iPhone 14 Pro with a minimal case. Sizing of phone cutout is 77mm across and 15mm deep. For my iPhone with a thin case this is a good fit but with enough room to slide in and out. If you measure your phone width and comment then I can create some custom sizes. This model has a large void to reduce the amount of filament to use.Printed in Overture PLA with 5% infill on a textured plate. Roughly 185g
