Spring desk thing bit holder

I had this nice spring triangle cup thing, which I think was intended to hold pens, but I needed to hold long shaft screwdriver bits, so I made this which goes over the top, and now all the bits stand up strait so you can see the business end.

An un-intended design element (happy accident): since the spring is in the way of all the outer edge hex holes, these can't be used for long shaft bits, but it does hold normal/small bits without falling through.
