Do not print without modifying the design first!
The original parametric OnShape design is here. You'll need to edit the variables to modify the design for your specific monitor thickness, phone thickness, phone height, etc.
This design snugly fits my HP display + iPhone 15 and will need to be modified for your devices. Every iPhone and display has a slight different shape.
