Remix of the original design for the newest generation tools, modified the screw hole size to for the 6-32 screw used on the new models. Also added optional retaining magnets 5mmx3mm behind the bit locations to keep the bits from working their way out under vibration from the impact/hammer functions of these tools.
PETG or ABS/ASA is recommended for strength.
