I ordered some of these
Storage Tubes from County Comm and I found them to be pretty useful.
I had a small screwdriver set that I often use and it was just a bit large for these tubes, so I cobbled this together with some PVC and fittings from Home Depot. Cost me about $3 since I wanted a threaded cap - would have been about $1 less with friction caps (shown with AA battery for scale).
Not nearly as fancy as the CC ones, but it is exactly the right diameter and length. I thought someone else might find the idea useful.
