I made the same extender from my Wave a few weeks ago. My wife got me a bit extender from Leatherman for Christmas and it is awesome!!! Well worth the $6 or so it costs. It fits the Leatherman bits and standard 1/4" hex bits. It also carries nicely in the sheath. Plus it is longer than a standard bit extender. If you haven't tried a Leatherman one its lightly recommended.
