This is a wall mount for the Apple watch that uses a North American Apple 'ice cube' charger.
The watch band can either drape over the edges, or it
...さらに表示 can be tightened around the back of the cylinder (tightening only works if you have a large band).
I successfully printed it using 0.2mm resolution, 3 shells and 20% infill, and it turned out well.
