Parkside electric screwdriver bit holder

Here my first model for my printer.I was really disapointed when I bought this screwdriver because I could not put standard screwdriver bit (for torx,…). So I did this one. It's a first version, I should improve for a better hold of the screw tip. Maybe adding a magnet.And maybe reduce width, I was not sure about the solidity, but this screwdriver have not enough torque to break the holder. Boost Me=)
