Let's get our hands dirty and make a "indestructible" USB drive~

The specific DIY process is as follows:

1. Find a piece of cardboard that is slightly wider than the USB drive, and cut a hole in it for the USB port.

2. Prepare a groove with a width consistent with the cardboard, pour in cement slurry. Note that since this is the side for the outer shell, it should only reach the opening of the cardboard. Insert the USB drive, then continue to pour the cement slurry on top, but not too much, otherwise it will be too thick.

3. Use a file to trim and polish the cement casing, making it smooth and flat, and you're all done!
