Smartphone attached stand

A very simple support arm that can be flicked out, so that phone can be placed on any surface and viewed hands free.
The brace and arm can be printed without supports by placing on the print bed with the hinge hole vertical.
I use a set of old credit cards stacked together to a height of 8mm to slide under as the printer begins to print the upper overhang of the hole.
The two parts are assembled using a paper clip or suitable wire.
The brace is made to suit Umidigi A3 Pro 10mm thick x 72mm wide phone (with case)
