A small screwdriver with bit storage that fits comfortably in your pocket.

additional hardware:

A neodymium magnet with 10mm in diameter and 4mm in height.

2x M3 nuts

2x M3 bolts with ~6mm in length

notes:

Print orientation as it is in the STL.

The cartridge fits 10 hexagonal bits.

The bits need to be 4mm wide, and the driver body will accommodate bits up to 30mm in length.

I used bits from an old screwdriver set I had lying around.
