Modular Beach Chair Holder

This solves a very special problem: beach chairs as common at north sea beaches usually have tables that are small, mostly foldable, and are prone to led slip things off when one wants to get in or out of the chair, or just by themselves. The holders have a notch that fits into the opening for the cover, the compartments hold phone, mug, or whatever you like.

The phone compartment has a PIP hinge so you are able to rotate the screen into view. To accommodate for different phone sizes, cut the compartment in Fusion appropriately.
