'Nina star' spin locker

This design prevents the ‘Ninja star’ bit divider on LTT screwdrivers from unintentional spinning out of place. Once the part aligned to the small gap between bit holders and is snapped on, it locks the black bit divider in the middle of each bit holder.

The small wall on top of the part my be hard to print. if you're having difficulties with printing it try increasing the fan speed and decreasing print speed.
