Gen 3 M18 impact driver bit holder. Easily holds 2 nut drivers. Many other bit holders don't really accommodate for nut drivers on the m18 platform so often times you lose the slot next to where the nut driver is supposed to go.
I used ABS for its strength but I suppose you can use whatever plastic you want.
MAGNETS REQUIRED - 8X3MM
GLUE REQUIRED - i used gorilla glue
SCREW REQUIRED - standard m18 accessory screw 2.5mm x 6mm screw
