Mini Precision Screwdriver with 14 bit holder

Mini precision screwdriver with integrated 14 bit holder. Based around a 4mm x 115mm magnetic screw bit extender.I used a screwdriver toolset from Lidl as the basis, but I believe any screw socket extender with similar length can work. Just search for "socket bit holder" or "socket bit extender" and you'll find what you need.The whole assembly is a pressure fit, so tolerances are important.I don't expect this to work well with every bit, since the tolerances for a good pressure fit are quite small... The best improvement to this will be to use magnets to hold the bits in place
