Key Features

Palm Swivel - The rear cap of the driver where it contacts with the palm swivels meaning that it does not rub against the hand whilst the driver is in use, providing extra comfort and usability.

Fully 3D Printable Design - No extra hardware required since the swivel is a press fit and since the shaft can simply be glued into place.

Optional D4x2 Magnet - Allows for the driver to hold bits in place with magnetism, improving the ease of use.

Assembly

1. Press the Palm Swivel into the handle of the driver and use the table if required.
2. Apply super glue to the shaft and slot it into the driver handle and allow time to dry.
3. (Optional) Apply super glue to a D4x2 round magnet and press into the shaft with the help of a 4mm bit and ensure there is time for the glue to dry before removing the bit.
