Precision Screwdriver Organizer

I purchased a precision screw driver from Princess Auto. I'm happy with the screw driver, but the plastic insert that holds all of the bits wasn't any good. The plastic was too flimsy, so when you tried to press the bit into its slot it collapsed so that it wouldn't fit. It was quite difficult to get them back in after removing them. As you can see in the pictures the plastic cracked in a few places.
So, I designed this to replace it and it's working great. Hopefully there is someone else
