Micro Screwdriver

    There are a lot of bit holders and screwdrivers on the internet to print, but I really hate to carry things on my pockets, so I tried to achieve the smallest design possible for these both functionalities.    I have been carrying one for three weeks and I could not be happier with the test. Best material for the job is PETG, but PLA was tested and works like a charm with just a little more work on adjusting    The same holes that carry the bits can also serve as screwdrivers just mounting the bits the other way around, so no empty space on the design. This idea force me to not use magnets, so bits has to stand by friction. The holes have to be softened by inserting and removing 10-15 times the bits before a confortable use. If you have to adjust the meassures anyway steps of 0.8% are recommended, but I will repeat the design on FreeCad soon so a proper adjustment can be done by anyone.    One hole tends to be harder than the others (I couldn't find the reason) and has to be adjusted with a lime. To make it a simple procedure the external radius of the hexagon is bigger so it is a single point of preassure and is the point to be adjusted with the lime. No more than 30 seg needed.
