4mm mini driver with magnet

needed to fit in a tight space rebuilding my ams came up with a mini 4mm driver fits IFixit tool kit. my first run kept dropping the bit so added an internal cutout for a 6mmx3mm magnet printed at .2 layer Hight 25% infill and 4 walls paused at 71 and used a bit of super glue to keep the magnet from attaching to my hardened steel nozzle while bridging over.
