That's the slightly modified bits holder for me. I've tried to explain that with the first image above, but probably in too much details smile It's not ideal, as the plastic there quite soft, but often it's sufficient to do the job, especially if you pinch the center with your fingers. I plan to print it in white PLA to make it more rigid in the middle, more visible, and maybe with a couple more slots for bits.
