I just wasted half an hour (mostly finding a dead motherboard and bending wire) making one of these:

I then threw out the cap to my USB storage device. Why doesn’t anybody sell them? Why are the holes for your keyring always on the part you use (thus weighing it down, particularly if it's sticking out of the front of a tower) and not the part that comes off? It's not easy to unplug by accident (I did squeeze it a bit removing some of the metal).

I think I’m just not looking in the right place. I can’t be the first person to have been annoyed with this. Lazyweb, please tell me where to go.

(Yes, the only thing I use it for is my SSH key.)
