Hello like minded out there.
Here I share with you my design of a bit holder for any 18V Makita Drill.
My design does have a notch so this "thing" sits properly and flush on the battery socket.
I also created different sizes to store different amounts of bits.
The "Extrem" version has a slot to slide in tree 12x18x2mm neodym magnets, to hold the screws or other stuff you may need.
