Magnetic screw driver for 4mm bits

Fork and modify to your hearts delight on OnShape.

Add a pause at layer height 60.4mm (layer 302 @.2mm layer height) and insert the magnet.

BOM:

1 m3 insert (up to 4mm deep)

1 m3 screw (8mm is a good size, but 6 or 10 would work)

1 m3 washer (a had a Delrin one in my parts drawer, but anything similar should do).

1 magnet 4mm diameter, 2mm deep (optional).

Hardware could be swapped out easily by forking and changing variables in OnShape.
