Based on the great and popular screwdriver. this modification uses a small ball bearing to improve the ergonomics even further.

Like many precision screwdrivers, the spinning back enables the screwdriver to turn without the need to lift the palm of the hand from the back. Consequently, constant pressure can be applied towards the screw.

This modification is based on the 5x3mm magnet version.


BOM:
  • 1x MR85ZZ Ball Bearing

  • 1x 5x3mm magnet (optional)

Tips for printing:
  • Use 100% Infill or multiple parameters for the shaft which the ball bearing will be pressed on

  • The use of supports is advised

  • PLA is sufficient
