Stubby Precision Screwdriver Bit Holder

This is a very simple stubby Knurled Precision Screwdriver Bit Holder. When working on some projects, I was not able to use my precision screwdriver handle due to lack of space and was tired of using an hex key to screw in socket head screws. I quickly mocked up a knurled nut that accepts 4mm precision screwdriver bits. There is a space for a 6x3mm magnet on the bottom which both helps the bit stay in space, and allows you to store it on any magnetic surface.
