An adapter to allow the use of normal bits with the Parkside electric screwdriver. Takes about 23 min and 2 g to print.

PLA with 95% infill seems to work well under reasonable torque, but you may want to use something stronger if you plan to manually turn larger screws.

Since different bits have different tolerances, you might want to glue e.g. a 6x2 mm magnet to the bottom of the socket.
