One of the most common problems with USB drives is the plastic casing getting cracked and breaking apart. It’s a shame that such a cheap piece of plastic might encourage some to drop another $20 or $30 on a new device. Of course fixing the plastic is never going to work as a long term solution – just a stop-gap.
Instructables has a nice USB tutorial on taking a UFD and turning it’s case into a nice, customized wood piece. Sure you could buy a fancy wood drive made from material carbon dated back 600 years or more, but sometimes making your own stuff is much more satisfying.

The USB tutorial displays 12 steps from start to finish with a list of equipment you’ll need, but after reading through the tutorial, I think a dremel would replace most of the tools required. And we all have one of those.
So get going and as Eric would say “go build something…”
