Dewalt driver bit holder

When I bought a new Dewalt DCD771 Lithium Ion drill, I discovered that it didn't have a spring clip to hold a driver bit like my older Dewalt 9.6 volt drill had. So, I designed this little clip that attaches to a hole in the handle that already has a threaded insert in it. There is one of the holes on both sides of the handle, so I made one for each side. I used a 4-40 flat head screw, about 3/8" long. If you use a longer one, it will protrude into the slot that the battery pack tab slides into,
