Very useful. I use it to hold feed balls for the wild birdies in the backyard. It looses "threads" at the corners of the rectangular section, maybe a round section would be better adapted.

a classical design. When taken in backpack, the parts come apart, which is a mild nuisance.

Snaps well into place, economic design. Reinforced corner well designed, but this may be the first thing that breaks when falling, so thicker could be an option, or a less deep slit. Screen protection is good, could be better with 0.5mm higher on the sides. Think about a fall with screen flat down on those concrete tiles with small pebbles embedded in the surface. Works well in natural PETG too. Never again have somebody taking your phone thinking it's theirs!

good print, mechanism works. Maybe not wide enough when holding phone in portrait mode, it topples because of train movements or screen taps.

part is perfect with correct dimensions. Even white PLA holds well in the dishwasher, comparatively to previous prints with a XYZ printer.m even better in white and translucent PETG.
