Craftsman Screwdriver Replacement Cap

I've had this nice, basic, magnetic tip Craftsman screwdriver for decades. When I purchased it, I also picked up a set of Torx bits to store in the handle.
The original plastic cap is lost to the ages. It was made of a softer plastic and was always the weakest part of the kit.
For many years, I've just used a cork to keep the bits in. Now that I have my shiny new CR-10s, a replacement cap seemed like a good project.
