Hex bit holder for blue Bosch drills that has a hex insert hole just above the battery. The holder has slots for 8x2mm magnets. It was made to fit my Bosch GSR 1800, but will most likely fit other drills that have hex insert slot.

It is a snug and reliable fit, even when printed on "crude" settings.
